Didn't play much (yet), but I think the only immediate complaint I've got is that traits that boost your stats almost feel kinda iffy since they're additive, rather than multiplicative, so they end up feeling a lot less impactful in the long run.
Like, "plain" removing 3 charisma barely means anything if you have 50, it almost feels like each trait needs a slight percentage to go with it, even if it's something small like 3 (+3%) or 3 (+5%) CHA getting removed, so that trait will always stay at least a little relevant all the way up at 1000 CHA, rather than you running around ugly, diseased, asymmetrical, purple with green polka dots, have breath that could kill a person, you're covered in warts, oozing fluids from every orifice and you're still able to easily chat with no issue because all those traits add up to like -30 CHA when you have 1000.
Also I guess I'm iffy about the character creation screen not telling you what the traits all do when you pick them, but I think that might be intended as a "mystery", so it's whatever.
