So I was wondering who was in charge of developing the game, and I was fearing it was Sonic Team, who's latest track record ranges from absolute crap (Sonic 360) to improved, but still mediocre (Secret Rings). Luckily, it seems Sega Sports is the developer, with Miyamoto overseeing the project.
Hopefully, this game is their way of saying "Sorry hopefuls, Sonic ain't in Brawl, so here's your Mario/Sonic crossover you've been wanting, in a non fighting but still competitive form".
I'll probably be buying it, but I just hope they get rid of the 4kids VA's because they make my ears bleed.
P.S. One last chance to leave your mind scarred with a mental image: Eggman vs. Bowser Olympic Sumo Wrestling.
