Seeing as the subject as gotten slightly further and further off topic lol
Spoiler Below
Yeah, and as I guess anyone who hasn't seen Sonic X yet doesn't plan on seeing it so will just let everyone know, that according to Sonic X (that was done by Sonic's creator) Eggman and Robotnik are not the same person. Robotnik is in fact Eggman's grandpa, and the creator of Shadow.
As for the latest Olympics, well the fact Sonic and the gang are in it make it pretty tempting to play, so if it were on display at the shops, I would give it a shot. But without a Mac or PC port, I won't ever get a proper play until emulation evolves enough of these systems I guess.
