What part is causing you trouble? There are some changes in the Enhanced Edition as far as running better on modern hardware and things like that. There may be mods in the workshop on Steam or Nexus. I played the original version. Its one of my favorite games, but tbh I think every game from that era that plays like Baldurs Gate sucks in the actual game department. Which is why people say to be a mage in this one, because the combat isn’t great, but especially as a fighter. Ultimately, the writing is what carries it.

EDIT: To add onto this, even though the overall gameplay is kinda bad (I think real time with pause is the worst control scheme in video games), it does do some subversive stuff with the writing that takes advantage of games in ways that you couldn’t with other media. I can’t say without spoilers, but because a theme in the game is that belief dictates reality (to an extent), some cool things can happen from your dialogue options that may otherwise seem mundane.
