I was in the stores the other day and I saw a copy of Sonic Gems Collection. you have sonic r
sonic fighters
and sonic cd
plus other games that you can unlock

The game features

-Sonic the Fighters
-Sonic CD
-Sonic R

Also, six Game Gear games as an added bonus...

-Sonic the Hedgehog 2
-Sonic Spinball
-Sonic Drift 2
-Tail\'s Adventures
-Tail\'s Sky Patrol
-Sonic Triple Trouble

Also unlockable is the Sega Genesis game Vectorman. There is one additional unlockable, but I haven\'t gotten it yet.

There\'s also a collection of 140 rare Sonic pictures that are unlockable by playing each game once, five times, for 10, 30, 50, and 60 minutes, etc. Lots of cool stuff to do in this game! Considering retail value is only 30, this is a must for any Gamecube owner.
