I would personally like nothing more than to be able to share the wasteland experience with someone, and it's been a dream of my brother and me ever since we first played Fallout 2 back in the day. However, some people suggest that it would deter from the original single player experience, and don't care much about it or would rather to keep it SP only.
What do you think about it, what are your pros/cons, and would you perhaps want to see it as a DLC, if not in the main game itself?
