I would recommend Thief if you are into stealth games. It was a love or hate game for many, but I thought it was great old school stealth experience.
LEGO Marvel is also really fun. I'm not a fan of the LEGO games but I liked this one.
ACIV if you are into the series. I'm not a big fan and liked the naval combat, but after about 10 hrs I got kind of bored with the game. I'll go back to it eventually but think the pacing could be much better and story is a bore.
I might think about buying tomb raider and pvz as people are suggesting it. Although pvz doesn't look like something I'd normally play so I will have another game with it in case. --- GT: Malicious Skunk
