Earlier today I was wondering what qualified me to review Sonic Generations, beyond my capacity for saying "god dammit." Yet after a solid 24 hours with this game not only are my eyeballs properly tracking its sidescrolling motion, I've recovered my innate understanding of the technical requirements of a solid speed-run through a Sonic world.
Sega is looking to reward that with a speed-run contest through the 3D version of Green Hill Zone in Sonic Generations, and you don't even need a full copy of the game to participate. Just go get the game's demo, and then practice, practice, practice (and say goddammit, goddammit, goddammit) until you get that time below 1:50. The video above (which is fun to watch even if you don't have the game) breaks down the optimal path with protips to help you get it perfect, but it still looks like it will take a lot of patience, practice and retries.
Capture your performance, upload it to YouTube, and you'll be eligible for some Sonic-themed prizes from Sega, but the bragging rights are the real reward. See the link for details and rules. The contest is open from today until Nov. 9.
