Not sure if anyone still reads this, but as to it changing something in bg2: It has for me. In bg2, the BG1 values for disarming traps, scribing spells and picking locks are used. It's kinda a pain, and while I do realise it can't use the bg2 values in bg1, is that really neccessary?
Anyway, was just surfing around and saw this, and I'm quite excited about it. I'm no modder (well, not yet. Might become. :-) ) but just being able to check out dialogue in such an easy format would keep me busy for a while. Lots of things I've always wondered about.
