That would be interesting, but there were things about The Colony that I didn't like. One of the things was that it was obvious that no one was trying to hurt one another during the clashes. I'm sorry, but if I have a weapon (club, stick, whatever) and you're trying to invade/take what I need to survive....you're not going to survive. I'm not just going to hold up the stick & act like I'm going to hit you with it.

As for if I think that something like this would be fun...hell yeah!
Perhaps rather than other sorts of weapons, paintball guns could be used.
