There is a natural ganging up or collusion effect in this game (Gang up on one guy to get him eliminated, or gang up on the perceived strongest). There is nothing wrong with this, it is part of the game, but it could make playing for money fraught with recriminations.

I would love to play online Monopoly, but you run into those people who will never make a fair trade (so you either concede a big edge to them, or the winner is determined more by luck than skill).

Multiplayer games that need or naturally develop player cooperation will always have these issues.

btw, my idea for a new approach to Risk in OOT, is to play Team Risk (2 players vs. 2 players) with full collusion between the team members (and you win as a team). That could be interesting.
