After a strong Xbox Developer Direct to kick off 2025, the future looks bright for Microsoft and its impressive lineup of first-party studios. With a rich history of iconic game series, especially following the acquisitions of Bethesda and Activision Blizzard, Xbox fans have much to be excited about. Whether you're reminiscing about the glory days of the Xbox 360 or eagerly anticipating the expansion of Xbox titles to other platforms like PlayStation, there's no shortage of legendary series to explore.
Here's a personal tier list of Xbox game series, based on enjoyment and impact over the years:

Simon Cardy's Xbox Games Series Tier ListS-Tier:
- Doom: The recent entries have solidified Doom's place as one of the best first-person shooters around. The upcoming Doom: The Dark Ages promises to continue this trend.
- Forza Horizon: Arguably the best racing games I've ever played, surpassing even classics like Burnout 3 and Burnout Revenge.
A-Tier:
- Halo: While Halo 2 and Halo 3 are among the finest campaign shooters ever made, recent inconsistencies prevent it from reaching the top tier.
- Fallout: I prefer the post-apocalyptic world of Fallout over the fantasy realms of Elder Scrolls. Power armor over dragons, any day!
If you disagree with this ranking, perhaps you're a staunch defender of Gears of War or have fond memories of Fuzion Frenzy. Feel free to create your own tier list and compare it with the IGN community.
