DC had some bomb-ass FPS games - Unreal, Q3, and the "homebrewed" Q1 [esp SimpsonsQuake]. It failed for other reasons.
A little side note... is the Xbox sold out where you guys live? Every place that carries it in my neck o' the woods is totally sold out [at least @ the stores I've been to]. the only things they have are a very titles [lotsa copies of Halo though] and accs. DOA3 is sold out too, btw.
