Two generations of hedgehogs collide today in Sonic Generations, and we've got the launch trailer to prove it. Just don't watch it if you're waiting on the PC version (November 4) or the 3DS one (November 22).
Or if you're in Europe for that matter (November 4). Or Australasia (November 3). Or Japan (December 1). If you're a PlayStation 3, Wii or Xbox owner in North America, however, feel free to celebrate! Pass out the Sonic Generations presents, light the candles on the Sonic Generations cake, and serve yourself a heaping slice with a little ice cream. Just try to avoid the classic era Sonic side of the cake, as it's been sitting around for a couple decades.
