Sorry, did not know that, the only IE game a played till the end was Icewind Dale 1, got halfway trough with BG 2 a long time ago, but my HDD decided to move to a better place (if you can call a junkyard that xd), reinstall, blue death, reinstall, run into a bug on the very first map (maybe couse vista?)... it's like someone cursed me so I could never finish the game xD That's why I started playing BG1 enhanced edition,this time i want to actually play it till the end from the very beginning xD
I played Neverwinter Nights 1 & 2 a lot though.
Sorry for offtopic.
You could also turn Sarevok in ToB through a series of 4-5 conversations.
