There are people who like to create, be it write, be it draw, be it act, or whatnot. And then there are those who like math. People can like both, but nobody can like them equally ... I am one of those people who likes writing, but hates (and by hates you should read loathes) math.
My hatred for math made me a little nervous about Money Idol Exchange. I mean, here we have a game that is, in effect, Magic Drop for bankers. That's right. You must collect and combine amounts of many instead of colors and shades. Collect five $1 and you get a $5 coin. Collect two $5 coins, and you get a $10 one. Collect five $5 coins ... well, you get the point. Needless to say, there's a coin for $1, $5, $10, $50, $100, and $500 (note: those dollar amounts represent six of Defunct Games ratings, with only 1000 missing).
The game isn't just for points, though. You are always fighting against a second player, be it a computer opponent or a friend (or, depending on how lonely you are, those could be the same thing). The one player mode works in the same way Street Fighter II did, you play a different person, eight in all, and then the game is over. However, even though you may shoot through the first two or three characters without any problem what so ever, the game does become extremely challenging. In fact, the computer becomes so difficult that it's almost annoying. Annoying enough to lower the ultimate grade.
The multiplayer is fun, a major improvement over the one player, but still the game just doesn't work like it should. Games like Tetris, Bust A Move (aka Puzzle Bobble), and Puyo Pop work because of their simplicity, Money Idol Exchange, however, is not simple, and not very much fun. If you must, get Magic Drop instead.
