Final Fantasy VII is the best RPG style video game, Sephiroth is the all time greatest bad guy, but all the FF series is really good except FF X-2, that game was a waste of money. Best RPG video game though is definately the Baldurs Gate series especailly NeverWinter nights.
As for REAL RPG's Dungeons and Dragons will always be the best, been playing for over 15 years and still love it!
BTW Final Fantasy VII is being made into a anime movie! I have the trailer if you want.
