Morrowind rocks. You're right, its so much easier (and more fun) to go hacknslash. Though, it was fun to play BG2 as a spellcaster, THAT was fun at the final battle where chaos ensued.
So far the absolute most fun I've had with any D&Dish computer game was taking my rogue character through Hordes of the Underdark by Bioware. Well-fortified and armed drow camp? Snuck up, killed anybody who didn't have backup nearby, and laid traps around all the little groups before calling in the henchcritters to start the carnage. There's a big battle midgame, and I just trapped the heck out of the battlefield and watched 'em drop. (Can you tell I like playing sneaky?)
Of course, there was the time I went through Morrowind as a werewolf...subtlety kinda went out the window on that one. :-)
