I have been playing BG3 for a while now (30h is a lot for me at the moment), and I must say I'm not having a lot of fun. There are several things that are bugging me but the greatest is that:
Companions do not make me want to use them, but the game lacks the benefits usually associated with playing solo. I *think* this one is pretty obvious if you've played a few hours, but the companions are unpleasant to say the least, and you aren't made stronger or getting more XP for soloing. That's the biggest issue for me, the alternative appears to be to abuse stealth, and that's not fun (because the enemies react as if it were 1995).
I saw that the latest patch was supposed to reduce their whining, but it's not enough IMHO.
