I'm 28, and I've played a lot - and I mean a LOT of RPGs. I probably wouldn't be able to list *all* of them (several I prolly just don't think of to put in the list, and some of them people may debate whether they're RPGs or not)
Baldurs Gate, Planescape Torment, Neverwinter Nights, Jade Empire, The Bards Tale (the newer version, never got to play the original), the Diablo Series, the Torchlight series, Avencast, several of the Elder Scrolls (especially Skyrim), Fable, Legend of Grimrock, Numen,
Other games I've loved: Kings Quest, Leisure Suit Larry, Monkey Island, Sam & Max, Zork, Zork Nemesis, Return to Zork..
Oh and I've also played plenty of the Japanese RPGs like the Final Fantasy series and stuff..
I also love tabletop games like D&D or Pathfinder. XD
