According to and NP Interview with Takashi Iizuka, one developer of Sonic Heroes, there are supposed to be many "surprises and secrets along the way." I also noticed that he ignored the example of Sonic CD that the NP reporter mentioned. Hmm, my guess would be that there are multiple unlockables: For video games: I'd say that they'd unlock Sonic CD and Knuckles' Chaotix. For mini-games: There are supposed to be a total of 8 types of mini-games. For gameplay: Create your own team of Speed, Power, and Flight. For other things: Who knows? And there's no Chao in this one? What's up with that? I liked the Chao Garden in SA2B, but the gardens in SADX were not improved very well. I was hopping they'd perfect the system with Sonic Heroes, but it looks like they didn't include it. What are you hoping will be unlocked in Sonic Heroes? and What are your thoughts of the elimination of Chao?
