What is the best XBox 360 game without a number in the title?

Bioshock is probably the best game on the 360 that is not a sequel.

I would have to say Condemned, not because its the best game but because its not your traditional first person shooter. Actually you barely get any guns at all, but that's a really good thing actually! Its all melee fighting and you solve crime scenes. Granted the sequel made everything better, the original is one of the first games to actually scare me since Resident Evil. And until Resident Evil 5 comes out these games are the best out there for a decent scare. Most people will argue F.E.A.R. is way better, ive played it and although it is very fun, it doest scare and it is just like every other first person shooter out there. The nice thing about condemned is that you can get it new for $20 or used for probably $15! Its definitely worth a try that's for sure! Oh and don't even bother playing it unless you do so in the dark, as it is a very dark and creepy game.

Oblivion (Has Prequeals but no connection between them, it is the elder scrolls saga)
