Best Xbox Game Series to Play In Order (2026 Guide)

Xbox's exclusive franchises have a habit of piling up sequels, remasters, definitive editions, and prequels until "where do I even start?" becomes the biggest barrier to actually playing them. If you've picked up Xbox Game Pass or just landed a great deal on a Series X|S bundle, sorting out the right order to play Halo, Gears of War, Forza, or Age of Empires can be more confusing than it should be.

This guide breaks down the best order to play each of Xbox's biggest series — covering both story chronology and release order where they differ — so you can jump in without missing context or wasting money on the wrong edition.

It's also just a smart way to shop. Buying a ten-year-old game blind, only to discover it's since been folded into a cheaper "definitive" bundle, is one of the easiest ways to overpay on Xbox. Knowing the order — and which editions have replaced which — means you buy once, in the right sequence, instead of double-dipping on games you already own in a worse form.

How We Ordered These Lists

For story-driven series like Halo and Gears of War, we generally recommend release order, since these games were designed to be played as they came out and their in-engine cutscenes, mechanics, and callbacks assume you've played the earlier titles first. Where a prequel exists (like Halo: Reach) we note where it fits in the timeline versus where it fits for a first-time player.

For Forza and Age of Empires, there isn't a connected story to worry about, so the "order" is really about which editions are worth owning today versus which have been superseded by remasters or definitive editions.

Halo — The Complete Series Order

Halo is Xbox's flagship franchise, and thanks to Halo: The Master Chief Collection, most of the mainline console games are now bundled into a single package on modern hardware. Here's the recommended order:

1. Halo: Combat Evolved (2001) — The original. Master Chief crash-lands on the ring-world Halo and the entire trilogy's stakes are set up here. Play the Anniversary edition if you want updated visuals.
2. Halo: Reach (2010) — A prequel chronologically (it depicts the fall of the planet Reach just before the events of Combat Evolved), but it was released later and was designed as a send-off, not an introduction. Most guides recommend playing it after Combat Evolved rather than first, since it's a self-contained tragedy that lands harder once you understand what Master Chief is fighting for.
3. Halo 2 — Introduces the Arbiter and expands the Covenant civil war. Essential for understanding the trilogy's back half.
4. Halo 3 (2007) — Closes out the original trilogy and remains one of the best-regarded entries in the series for its campaign and multiplayer.
5. Halo 3: ODST — A side story following the Orbital Drop Shock Troopers during the events of Halo 2's finale. Optional but adds atmosphere and a great soundtrack.
6. Halo Wars — A real-time strategy spin-off set before Combat Evolved. Skippable if you only care about the FPS story, but it fills in Covenant/UNSC history nicely.
7. Halo 4 (2012) — Starts the "Reclaimer Saga," introducing the Didact and the Forerunners as a bigger threat.
8. Halo 5: Guardians (2015) — Divisive among fans for its marketing and campaign structure, but necessary if you want the full context for Infinite.
9. Halo Wars 2 — Bridges the strategy spin-off timeline forward; optional.
10. Halo Infinite (2021) — The current mainline entry and the best jumping-on point visually and mechanically if you'd rather start modern and work backward instead.

Best value pick: Halo: The Master Chief Collection bundles Combat Evolved, Reach, 2, 3, 3: ODST, and 4 in one package, so most of this list is a single purchase (or included with Game Pass).

Gears of War — Story and Release Order

Gears of War's story order and release order match up almost perfectly, which makes this one easy:

1. Gears of War (2006) — Delta Squad fights the Locust Horde on Sera. The Ultimate Edition is the modern way to play this on Xbox Series X|S.
2. Gears of War 2 (2008) — Raises the stakes considerably and deepens the cast, particularly Dom's storyline.
3. Gears of War 3 (2011) — Closes out the "original trilogy" and resolves most of the Locust/Lambent conflict.
4. Gears of War: Judgment (2013) — A prequel following Baird and Cole before the first game. Skippable for newcomers, but fills in backstory for series veterans.
5. Gears of War 4 (2016) — Jumps forward a generation to JD Fenix, Marcus's son, and introduces the Swarm.
6. Gears 5 — Continues directly from Gears of War 4 and puts Kait Diaz at the center of the story. Widely considered one of the series' best.
7. Gears Tactics — A turn-based strategy spin-off set before the original Gears of War. Great if you enjoy tactics games, otherwise optional.
8. Gears of War: E-Day — The upcoming prequel depicting Emergence Day, the very start of the Locust War. Chronologically first in the timeline once released, but designed to be played by people who already know the cast, since it's building on decades of established lore.

Recommendation: New players should start with the original Gears of War and go in release order. Save Judgment and Tactics for after you've finished the mainline saga, since both assume you already care about the characters.

One thing that trips up new players: Gears of War's story leans heavily on tone shifts between entries. The first three games are grim, horror-adjacent survival stories about a losing war; Gears of War 4 and Gears 5 shift toward a more hopeful, generational-legacy story about rebuilding after that war ended. Going in order makes that shift land the way it's supposed to — jumping straight to Gears 5 without the earlier games means missing why Marcus Fenix is such a haunted, reluctant figure by the time his son takes over as the protagonist.

Forza — Horizon vs. Motorsport, and Which to Play First

Forza isn't a single continuous story, so "order" here really means understanding the two separate sub-series and which entries are current.

Forza Horizon (open-world arcade racing)

Forza Horizon games are mostly standalone, so you can start with the newest one without missing anything:

1. Forza Horizon 4 — Set in a fictionalized Britain with dynamic seasons. Still fun, but was delisted from digital storefronts, so it's harder to pick up new.
2. Forza Horizon 5 (2021) — Set in Mexico, widely regarded as the series' best-looking and most content-rich entry to date. The natural starting point for most players today.
3. Forza Horizon 6 — The newest entry, expanding the open-world formula further. Recommended jumping-on point if you want the latest content and car list.

Forza Motorsport (sim racing)

The Motorsport line is Xbox's more simulation-focused racer, rebuilt from the ground up with the 2023 reboot simply titled Forza Motorsport:

1. Forza Motorsport (2023 reboot) — A full rebuild of the series' physics and career mode. This is the correct starting point rather than hunting down older numbered entries (Motorsport 7 and earlier), which have largely been delisted or superseded.

Bottom line: if you want open-world fun with friends, start with Forza Horizon 5 or 6. If you want a more serious sim-racing career mode, go straight to the 2023 Forza Motorsport reboot.

It's worth noting that Forza has a much shorter shelf life per entry than Halo or Gears — older Horizon titles get delisted from digital storefronts once a new one launches and their online services eventually wind down, so unlike Halo or Gears there's rarely a reason to hunt down a "classic" numbered entry once a newer one exists. Buy the newest one you can, rather than trying to complete the series historically.

Age of Empires — Which Definitive Edition to Play First

Age of Empires on Xbox is almost entirely made up of "Definitive Edition" remasters of the classic PC strategy games, so the order here is about historical setting and mechanical complexity rather than a connected story:

1. Age of Empires: Definitive Edition — The original 1997 game, remastered. A good history lesson in how the series started, but the most dated mechanically.
2. Age of Empires II: Definitive Edition — Widely considered the most iconic and best-balanced entry in the series, covering the medieval era. If you only play one classic Age of Empires game, make it this one.
3. Age of Empires III: Definitive Edition — Moves into the colonial era (1500s–1800s) and introduces a home city progression system between matches.
4. Age of Empires IV: Anniversary Edition — The newest mainline entry, built as a modern successor rather than a remaster, spanning multiple historical civilizations and campaigns from the Norman conquest of England through the Mongol invasions.

Recommendation: New strategy fans should start with Age of Empires II: Definitive Edition — it's the most refined entry, has the largest community and multiplayer population, and is the game most "Age of Empires" conversations are actually about. Move to IV afterward for modern production values, and treat I and III as optional deep cuts for series completionists.

Final Tips

A few general rules apply across all of these franchises:

• Definitive/Anniversary/Ultimate editions are almost always the version to buy on Xbox Series X|S — they include visual upgrades, bug fixes, and sometimes bundled DLC that the original releases lack.
• Xbox Game Pass frequently includes entire franchises at once — Halo: MCC, Gears 5, Forza Horizon 5, and Age of Empires II/IV have all rotated through Game Pass, so check your subscription before buying anything individually.
• Prices on remasters and definitive editions do fluctuate — bundles in particular go on sale far more often than most players expect. Track individual game listings to catch a base price drop before buying, rather than assuming the list price is the best you'll get.

Whichever franchise you're diving into, starting with the right edition and the right order will save you both money and confusion — and give you the full context these long-running Xbox exclusives were built around.
