My thoughts (I have all the games xcept IWD 2, any day now [img]smile.gif[/img] )
(1) Fun game, but low on RPing. If the storyline didn't pull you in in Morrowind, this one will leave you out in the cold (pun intended.)
(3) Incredibly high on plot. Makes Lord of the Rings look like a Dick & Jane book (ok so I'm maybe exaggerating a little.)
(4) One of the best balanced games between plot and action I've ever found, get it if you're going to get...
(5) I LOVE THIS GAME. It is the only RPG that I have beaten more than once, save NWN and Morrowind. INCREDIBLE.
(6) Sweet games also. There are some points where the game balance just isn't there though, and you have to wander looking for encounters. Still, you can get them both in a bundle for 20$ Can, soo.
Also, I have NWN, and it's fun, but you NEED to play multiplayer, or else the hefty price tag ain't worth it.
