Since no one here has mentioned it, i'm going to throw Dark Souls into the mix if your into RPG's
Although with Dark Souls be warned that it is an extremely hard and frustrating game which will probably lead to you pulling out a lot of your hair, but if your looking for a really challenging RPG i would say Dark Souls... otherwise, Skyrim is another very good choice...
Other games: Lego series has some fun games which don't take much thinking and can be quite entertaining... i know my g/f loves them and has bought pretty much all of them for me so she can play...
dragon age for RPGs
