My favorite Sonic game is SA2. I just love almost everything about it. *coughDrivingstagescoughMadSpaceCough* The story, the level design, the characters, the music, Oh GOD THE MUSIC, *ahem* added up to a fantastic game. The Sonic and Shadow stages are a blast, especially with the tight controls. The Mech stages are also really fun in their own way. Some of the Treasure Hunting levels were fun although others were annoyingly unfair. The Chao Garden was amazing. Me and my brother have raised at least 20 Chaos and one of them is solely fed unicorns. (it is awesome). The Multiplayer is an absolute blast and I've had a lot of fun with it. Overall, it is not only my favorite Sonic Game, but my favorite game ever. Also, out of Sonic, Silver, and Shadow, Sonic's my favorite. His personality and "never say die" attitude just bring a big goofy smile to my face and he represents everything that was awesome about my childhood. (which was around 50% of it)
