Xbox for me. Ironically some of the Xbox’s best games were from Sega including one of my favorite games ever with Jet Set Radio Future.
But Halo CE truly being a killer app that led to endless LAN parties, then Halo 2 taking the LAN party experience online, adding my introduction to Elder Scrolls series and golden age BioWare, and Fable, Xbox had some great games.
I also really enjoyed other great FPS titles like Half Life 2, Unreal Chanpionship, and Doom 3.
