>>713262545I did my fourth playthrough recently and went full evil for the first time, hoping to mimic practical incarnation to some degree - I was bitterly disappointed by the roleplaying options though, good alignment feels vastly superior in every way. Most of the evil things just came down to me killing people impulsively, there weren't really any implications and your party doesn't really react.
I was looking forward to pushing Morte into the pillar of skulls and leaving him there this time, as it was about the most evil decision I could think of, and he just leaves your party and that's that. The end of the game in the Fortress of Regrets feels completely written for good alignment characters, and being evil just felt hollow by the end of the game.
