I've just finished inFamous 2 both Good and Evil, and it was indeed better than its predecessor. I honestly couldn't stop playing it is that addicting, so I think it would be a purchase you wouldn't regret. As for Batman Arkham City, I really don't know much about it save that it looks pretty good from what I have seen.



Uncharted 3 I would have to say definitely yes. Especially if you love platforming, adventure type third person shooters. The multiplayer looks very promising, as does the initial storyline. I myself look forward to purchasing it greatly.What game should I purchase now for keeps?
Infamous 2 is supposed to be better than the first one so, I would get that. But it's up to you :)
