Here's a whole bunch of Sonic Generations 3DS screens for you to enjoy. You can print them out and glue them to your cat, or mix them up with some spaghetti to make your aunt's famous Sonicscreengetti. Your choice!
The portable versions of Sonic games are nearly always consistent in their quality, so even if the console game doesn't pan out so well, I'm looking forward to enjoying this one. It will probably be good. Maybe. I hope.
