Following a strong showing at the Xbox Developer Direct to start 2025, Microsoft and its impressive first-party studios are looking strong. But which Xbox game series excites you the most? Which provided the most enjoyment during the Xbox 360 era? Or, if you've never owned an Xbox, which series are you most anticipating on other platforms like PlayStation, as Microsoft continues to expand its game library's reach?

There's a wealth of legendary game series to choose from, especially considering Microsoft's acquisitions of Bethesda and Activision Blizzard. This tier list includes any series associated with Xbox, Bethesda, and Activision Blizzard with multiple entries—sorry, MachineGames and Indiana Jones! A sequel would certainly change that. This isn't an exhaustive list of *every* Xbox game series, but it covers significant current and historically impactful titles. Here's my personal tier list, based solely on my enjoyment over the years:

Doom easily earns an S-tier spot for me. The recent entries are among my favorite first-person shooters, and Doom: The Dark Ages looks like id Software is maintaining its high standards. Forza Horizon also sits in S-tier; arguably, outside of Burnout 3 and Burnout Revenge, they're the best racing games I've ever played. Placing Halo in A-tier might raise eyebrows. While Halo 2 and 3 boast incredible campaigns, I can't ignore recent inconsistencies preventing it from a top-tier ranking. I'm also more of a Fallout fan than an Elder Scrolls one. Power armor over dragons, any day!

Disagree? Think Gears of War is Xbox's best? A staunch defender of Fuzion Frenzy? Create your own tier list below and compare your S, A, B, C, and D tiers with the IGN community.
