It's like a more in depth MONOPOLY. Great for kids on a rainy day.
I loved the cutesy Super Deformed art style. Gameplay is fun because its like a boardgame. In fact, it say BOARDGAME right on the Cover, so you better have some friends. The game is playable in single play, but the only reward is strange dialogue between a cat and people, aliens, television, and maybe the occasional cactus. The dialogue isn't all that witty, but if your into ridiculous things the single play is for you.
The multiplay even has the "Pass go collect $200" thing except the value can be higher due to a mechanic where the received capital is a percentage of your current assets. Also, a point system is involved. You earn points by paying money to the other players at their shops (this is mandatory by the way). With points, you can activate events that can completely screw your opponents and make them mad at you. There is even one ability to instantly end the game and win.
Overall it's very fun (assuming all your friends like this sort of game) but not really if you're alone.
