Quote of the day right there. I don't even care about Sonic 4's criticism, I'm just all in favor of face-fucking awesomeness. That's going in my sig.
Also, what Aquaslash said: It's a "Best Of" introduction to the rest of Sonic 4, which'll be like two or three more episodes. Get over it.
One thing I probably won't get over is the price, though. $15? Really, SEGA? I don't fucking think so. I'm hard pressed to find a WiiWare game that costs more than 1,000 Wii points, and the ones I did were Cave Story and Sin & Punishment at 1,200 points, and Final Fantasy CC: My Life as a King and World of Goo for 1,500 points.
Okay, it's not unheard of, but it's rare. I'll pay for it, but it better be fucking good.
