Ignore the current gen games man. Old school all the way! Star Control 2 is incredible and freeware/opensource. Planescape: Torment is amazing. Fallout 2 is awesome. Monkey Island is the funniest game (subjective) you'll play. The only problem is finding these games; very unlikely you'll see them in stores.
Edit: Actually Monkey Island has remakes available on Steam so that is easy to find. As well as Fallout 2. So the only hard one to find would be Planescape now that I think about it.
