I would recommend FF7 Crisis Core if you havn't played it. I would also recommend Mega Man Powered Up you'll be spending hours and also creating levels too.

Killzone 2

I would recommend Professor Layton and the Curious Village and Animal Crossing

Play the dam game

Metal Gear Solid 4 would be my oick but might change once Final Fantasy Versus XIII is released sooner or later.
