I can't stand Risk because Risk rewards inactivity. It is almost never optimal in Risk to attack another player (although limited skirmishes are fine), because even a successful assault will badly damage your own forces leaving you vulnerable. The way to win Risk is to convince other players to attack each other and then clean up in the aftermath. This is ok for players that are new to the game because they'll actually attack each other (they don't know any better). But experienced players will almost never attack, resulting in a stalemate.
