What can I say, I have a gift for these things. Except for that damn godmode bastard werewolf.
Well, it was an IE game, and all IE games have the same basic style which I have honed with multiple playings of BG, BG 2, IWD, and PS:T which I played to death (30 to 40 times each) so when IWD 2 came out it was pretty much a breeze. Add to the fact that I know 3e decently well I was able to make a fairly optimized and powerful party that pretty much owned more than half the game.
Who is better to know the game than the those who created it? I trust you guys enough to give accurate information on game length in a game you created.
