temps: Just wondering if this game is censored, edited, or otherwise changed from the original version (aside from technical updates like new resolution and widescreen capabilities)?
The short answer to your question would be "yes". Examples:
1) Kagain's mini quest:

https://www.gog.com/forum/baldurs_gate_series/nashkel_winter_wolf_pelts 3) Spell descriptions, such as this one:
Tenser's Transformation:
Original: "... for when the wizard casts the spell, he undergoes a startling transformation. The size and strength of the wizard increase to heroic proportions, so he becomes a formidable fighting machine."
EE: "... for when the wizard casts the spell, <PRO_HESHE> undergoes a startling transformation. The size and strength of the wizard increase to heroic proportions, and <PRO_HESHE> becomes a formidable fighting machine."
What the "<PRO_HESHE>" part does is it changes the pronouns between "he" and "she" depending on your main character's gender. The original game never cared about such "issue".
I'm not arguing whether these changes are for the better or worse. I'm simply explaining why I'm saying the answer to your question is "yes". There are many, many instances of subtle changes such as these.
Majority of players answer "no" simply because they aren't even aware of these modifications. And if they do, they probably don't care. You only notice such changes if you have spent a fair amount of time replaying and modding the game and looking into the game's codes and texts.
