Well that's pretty comforting. So I won't be disappointed.
My collection is as follows:
Halo 3
Halo 3 ODST
Resident Evil 5
Assassins Creed
Assassins Creed II
Left 4 Dead 2
Fable 2
Star Ocean: The Last Hope ( I think thats the one)

And thats pretty much it. I had Lost Odessy but that went missing lol
So as you can see, for the most part one play-through and thats the end of it.
