Next point, side quests. Most of the side quests in this game are about helping people. I know there are quests that you can finish in an evil way, but those are far and few between. Most quests are your character helping someone find an item or resolve a dispute. Now, you could say, why don't you just not do those quests? Well, because that's BORING! Why can't I get each quest have an evil option? Say someone gives you 500 septims to deliver to their friend in Whiterun or something, and you go to deliver them but instead keep them for yourself and rub it in the persons face. That's just an example but you get my drift.
Finally, infamy. You could be the Listener of the Dark Brotherhood, the Guildmaster of the Thieves Guild, you could've murdered every single person you can... and yet the average person in a town will STILL act like you're a completely normal person. In Oblivion, at least people would hate you and some would even attack you just for being infamous. It makes no sense to me why they would take this out and ruin the immersion of being a bad guy! I thought this game was about playing how you wanted to play, but even if my character does the most evil things he can and ignores all of the sidequests, the mere fact he is Dragonborn means the whole world love him. Not cool.
