Western flavored RPGS have always done very well on the 360 (and the original Xbox) in comparison to the other consoles. Bioware, Bethesda, Lionhead. All developers of many million plus selling RPGS.

 Guess I've heard the "only shooters sell on 360" line so much, that I had started to believe it was true. 

Hehe yeah. Now I certainly wouldn't deny that the FPS genre is very strong on the 360 of course!

I think maybe a lot of it has to do with the fact that many games from the original xbox were also on the pc and maybe the brand attracted a lot of pc gamers that decided to by into the console market? And since pc was the original (and arguably still) main platform for WRPG's, there was some sort of overlap?
