Microsoft's Xbox Developer Direct has generated considerable excitement for the future of Xbox gaming. But which Xbox game franchises truly stand out? This tier list considers series from Xbox, Bethesda, and Activision Blizzard (requiring more than one game entry). Note: This isn't an exhaustive list of every Xbox franchise.

Here's one perspective, focusing on personal enjoyment across the years:

Doom easily earns an S-tier ranking for its exceptional first-person shooter gameplay, particularly the recent entries. Forza Horizon also receives an S-tier nod; arguably among the best racing games ever created (rivaled only by Burnout 3 and Revenge). Halo's placement in A-tier may be controversial. While Halo 2 and 3 boast incredible campaigns, recent inconsistencies prevent a higher ranking. Personally, the Fallout series holds more appeal than Elder Scrolls (power armor over dragons!).

Disagree? Do you believe Gears of War reigns supreme? Or is Fuzion Frenzy your champion? Create your own tier list to compare your rankings with the IGN community.

Feel free to share your own Xbox game series rankings in the comments, along with your reasoning. Mention any notable franchises we've overlooked!
