Unless you do obviously dumb things, like not doing anything at all and letting the enemies hit you, you literally could not fail at baldurs gate on default difficulty. I actually find it way too easy to succeed and far too forgiving. You could genuinely go through the whole game with your “picked random everything” character. Youll get your ass kicked a few times, but youll never get stuck anywhere. The only part thats complex is the story IMO. There are dozens of alternative endings and secret story bits and hidden interactions between characters. Almost every quest, no matter how small, has multiple endings. You could probably sink 1000 hours into BG3 without going through most of the story content.
