I played the three Modern Warfare games and enjoyed them, but I'd say that only the campaign of the first one (CoD4) was truly memorable. I've enjoyed the multiplayer but you really have to invest yourself in it. Very different than Halo's.
Personally, I'm a little peeved that Don't Starve is only on the PS4. I mean, come on, I know the PS3 can run it. Oh well, at least I can start to stock up on PS4 games.
