"For those of you eagerly awaiting Sonic 4: Episode II, listen up. SEGA is promoting Sonic CD as the direct prequel to Sonic 4. So not only is this a super fun Sonic game for XBLA, it potentially offers tips about SEGA’s upcoming projects. That’s two reasons to get it, I shouldn’t have to give you a third."
