Tyranny

• Decide what kind of person your character is from the start and roleplay them, you'll enjoy the choices more rather than trying to min-max stuff.

• Loyalty/Fear aren't a strict positive negative scale. You get stuff for having people and organizations like you OR hate you, so neutrality is the least rewarding place for them to sit mechanically.

• Unless you're playing the really hard modes, don't worry too much about what's viable. You can pretty much play whatever you want just like you could in PoE, though you don't have the option to make custom party members, you basically build the ones you get between two trees they each start with unique to each character. Your main character can do whatever you want.

• Your whole party gets experience towards their skills when using one, like lockipicking a chest gets everybody some XP in mechanics or whatever.

• Oh, and don't skip the little quiz thing during character creation, at least not the first time through. It's basically doing world building that other characters will know your character for.
