I've got to say, I find even Monopoly to be a terrible game. My strategy for the game can be summed up as: "buy the property if I can, otherwise pay rent if I have to". I almost never stray from that strategy, and even when I do, it's not like those exceptions make the game any more interesting.
The "fun" part of Monopoly is trading with other players. It's actually a pretty acceptable game as far as diplomacy goes. The worst problem with the game is that it very quickly devolves into a situation where two players have a decent chance to win, everyone else is royally screwed, and the game still has about an hour to go. Also, it's terribly reliant on luck: while it is possible to actually be good at Monopoly(i.e. there are strategies and skills that will seriously increase your chances of winning), a few bad rolls and/or a player adamant about not selling X property or trading Y player (this happens a lot IME) can leave you completely out of the game.
