I'll buy it if it has a Chao garden like in Adventure 2.
I've heard good things about the Gamecube 'Battle' Version.
But I've never owned a Gamecube so i've never seen alot of the add-ons to the Chao Garden.
Which saddens be greatly as I loved the Chao Garden.
Other than that, The last Sonic game I even looked at was Unleashed, and it took me approximately thirty-two seconds to decide that Sega has killed the real sonic and replaced him with a much more talkative, childish, annoying, bitch.
