right, so far I've got these ones...

Assassin's Creed 2
Fifa 10
Sega Mega Drive Collection
Farcry 2
Soul Calibur 4
Unreal Tournament
Dead Space

Got the first two with the console the rest were budget pre-owned purchases, what to buy next?

These ones are on my "interested" list.
COD: MW2 (inevitable)
Uncharted 2
Metal Gear solid 4
GTA: IV
Little Big Planet
Fallout 3
Ashes Cricket 09
Tiger Woods 10 (or maybe an older version)
Topspin 3/Virtua Tennis 09 (can't decide)
NHL 09
Ratchet And Clank (probably Tools of Destruction for now, the new one is still expensive)

As you can see I like my first-person shooters and my sport games but am open to other suggestions, although I'd appreciate it if no one bothers mentioning car racing games, there really wouldn't be any point.

Cheers.
