Low INT is weak, but also extremely fun for roleplaying. The number of skill points you get when you level up is based on your INT. Base it's 10, but it can go up to 15 with maxed INT.
Conveniently doing a run right now since I never completed it thanks to a game breaking bug back in ~2011. It do feel fun just charming people to get your way. But man the game is pure jank (at least on Windows). Routinely thinking "I could be playing F4 right now" but the writing keeps me going.
