Yeah, that UI they introduced later was a bad move, should have stuck with the original. But it's not horrible.
I don't think the EE changed the content much at all -- you can actually edit the ini to eliminate the EE NPCS. One line for each. Some the like <npc_name exists=0>
There were EE characters I didn't like and I'm just not interested in evil paths but the engine improvements were are substantial. I couldn't imagine going to back to the original pathfinding.
The thing you have to remember is that there was dogpile effect after the game got review bombed for (shock, horror) having a character who changed gender. Somehow that ruined some people's childhoods. So there were review-bombs by people who clearly hadn't played the game and then other jumped on the abuse train. It's just fun to get your kicks in when someone is down . . .
Which is sad because some haters ranting at computer screen ruined people's careers.
Don't get me wrong, I have my critiques of the company -- indeed I've been banned from the EE forums -- but the engine really was improved and the hand painted backgrounds have aged much better than, say, NWN1. (god that game is ugly)
Personally, I really like the Wild Mage NPC but have no use for the vampire, monk or blackguard. The bear is kinda funny.
Get it. I think I saw it for something like 7 dollars a while ago.
