Doesn't take away from my original love of the game. And it's not really fair to compare to the replay value of the first game, because I've never played another game over and over again like that.

The one positive about NG+ I'll mention though is since I already know the story I'm able to enjoy the side quests more (my first playthrough I went QUICKLY through the main quests, and then did the side quests afterwards). There is a ton of depth and thought put into all the side quests and characters/tribes.
