I am always a good character. Except in Mass Effect. I am the biggest dick there could possibly be in that game, but I did feel bad when I shot Mordin, let Samara kill herself, and shot the Ardat-Yakshi
. I guess I had a few paragon decisions here and there like saving the council.
Mass Effect was the first game I ever played where making the evil choices didn't make you feel like you get screwed out of things. In other games being evil means higher prices and less side quests from people because you tell them off.
