Let him be... RPG for PC, try Dragon Age, that's the hottest RPG out for PC at the moment. I personally recommend highly Fallout 3. I rate that better than Oblivion because the setting is awesome and the gameplay is great. Better story too. I don't like strategy games, I can't be fucked to think.
Try Command and Conquer series Diablo 2 or 3 if ur willing to wait Starcraft Perfect World Fallout new las vegas if ur willing to wait lol Torchlight The total war series
RPG:in terms of gameplay i think Baldur's Gate better than Dragon Age. Even Neverwinter2 Recent FPS/hack-n-slash PC games:Resident evil5, prototype, bioshock
I know this might be a bit of a different angle to what you said you like, but I hear good things about Tropico 3. There is strategy involved i think.
if you have not played Company of Heroes, you should definitely play it. one of the best strategy games. Game of the year 2007
i've also heard awesome things about Mass Effect. It's supposed to have an awesome story line with real science as a base... even includes an interview with a well known physicist...
