I have incredibly fond memories of the first four SSX games, especially Tricky and On Tour. I got gold medals on every track, race and showoff, with every character in Tricky, but then my house was robbed and my GameCube was stolen along with the memory card with that data on it. Heart break ensued. Fortunately, On Tour was incredibly fun and gradually mended my broken heart.
Therefore, while I am incredibly pumped for Mass Effect 3 and looking forward to it very much, the reveal of a new SSX game wins it for me, especially one set in crazily extreme conditions.
