I used to play the Hell out of some Donkey Kong back in the day. All the way from the original back in '85, all the way through to the bad ass DK 64 in the '99...
The other week I picked up Diddy Kong Racing for the Nintendo DS.
No where near as good as the DS version of Mario Kart. With it, you can race people from around the world on the Internet. This past weekend I watched the end of the Daytona 500. After having no crashes for like the first 3/4ths of the race all Hell broke loose and people started spinning out right and left.
I feel like an idiot saying it. But, that was kinda cool.
