Xbox Live Arcade was the biggest letdown for me, they had a good idea however.

When Microsoft announced that they were bringing out a Arcade to play over XBL, I thought to myself awesome! Finally I can play all the oldschool games, and there might even be some multiplayer action. Then ofcourse, the money. Microsoft=money, so we had to pay for all these different games, and of course it wasn't a couple bucks, but some games would cost up to $25. From the games that I did play, for free, I rather enjoyed them. It was fun to play all the classics again, on the XBOX. I also thought that the Demo was a good idea. You were able to download 25 min demos of games, for you to try out before you bought them. But that was about the only good thing about the XBL Arcade. If you have money and nothing to spend it on, then this is a game for you. For the rest of us, Im going to have to say pass on that. Too much money to spend on has-been games with not enough multiplayer support, for it to be called XBOX Live Arcade.
