Probably either Pokemon or RuneScape. Yeeeah, that's right. Although I haven't played many RPGs. Another one that's really awesome is this DS game called Custom Robo Arena. It's really awesome, you get to buy parts, rank up, fight people.. And there's online play, though it's not that active.
I hate WoW. LOTRO is much better. You can actually get in game player help when you are stuck on a quest. I tried the free trial and NO ONE would help me on the quest. I would not recomend WoW to anyone.
FF is always good, so are the Fable and Mass Effect series. For computer games, I'd have to say Runescape, simply because it's free and it supports both sets of players.
Never really got into the eastern RPGs (IE, final fantasy). My favorite has to be Mass Effect (1) though. Strikes a good balance of action-adventure/shooter and RPG.
I can't say I'm a hardcore RPG fan, so that's why I'm not crazy about games like Dragon Age: Origins.
