It wasn't always like this

Mario & Sonic at the London 2012 Olympic Games might have been SEGA's biggest seller of last year, but don't let it fool you: it's an uneasy alliance.

Sonic Wrecks recently posted a video from SEGA's official library that dates way back to 1992, from a time when the plumber-hedgehog rivalry was at boiling point. Just watch the first minute of this video and revel in the brazen way SEGA took on Mario way back when.
