Speaking of Monopoly glitches, I've noticed one that annoys the crap out of me.
When I play Monopoly, I try to get the Get Out of Jail Free cards. No reason, it's just something I do. I'll buy them from other players for twice their value (i.e.: $100), get them in trades and keep them when I do get them, paying to get out of jail instead.
So, I do the same think when playing this game. Except, occaisonally, when a player lands on Chance/Community Chest, they'll draw the Get out of Jail Free card even though I've got it and have never used it. Then, I lose it (unless, of course, it was I who landed on that space and drew the card...). It also annoys me that I can't buy/trade for this card from other players.

Anywhoo, speaking of DS games we'd like to see, I agree that a good Risk game on the DS (with Wi-Fi, of course) could be a good seller. Personally, I want Stratego on the DS. A lot.
