Oh, I've played Mario Cart for the GBA, it's a blast. There's lots of nice games for the DS, don't get me wrong. It's just that I find the strategy games lacking. Usually, due to too much corny written dialoge between levels and crap. I've heard that Puzzle Quest is a really good game for the DS, and I might have to buy it to check it out. Also, Peggle for the DS is coming soon
