Next 2 single player games to get for my 360

[tomanders91]

Im looking for 2 new single player games for my 360, just wondering what do you think i should get? Im thinking about getting:

Halo 3 (worried though since its mainly multiplayer, how long is the single player?)

Stranglehold

Fifa 08

Not sure what else, i have dead rising, crackdown and forza 2 and enjoy all of them.

Thanks.

thanks for the suggestions, sorry forgot to mention, i have bioshock on pc, and used to have saints row on my old 360.

Thanks.

PS: Anyone got a 48 hour live trial i could try? Just to see if it works for me?
