Im starting feeling like CRPG just cant do evil route very well. I mean its a night and day difference between something like Tyranny and Crusader Kings with how you deal with "evil choices".
But Tyranny does a great job? It's just that BG3's setting is so biased towards good that all evil is cartoonish.
Tyranny at best is Neutral. If you take evil decisions (and there are a couple) you basically lose out chunk of story and get bad ending (like you have to basically skip the entire DLC if you are lawful evil?). The worse case of this is with a vendor in prologue. If you follow lawful evil you miss out entire tree of skills. You can be devious here and there but Crusader King beats it by a long mile for sure lmao.
