This 32X game was the first major spin off for a Sonic character, in that it was Knuckles in the starring roll and the first appearance of the 'Chaotix' group - which admittedly was nothing like what you see today. Vector was thinner and astoundingly somewhat religious, Mighty was Mighty - his second and final appearance to date whilst Charmy was older, less cutesy and even smaller than he is now. In fact the only one who's not changed much is Espio - the Chaotix character who's appeared in the most games. Hmm. All that and not a hedgehog in sight, well, except for Metal Obviously.
