I don't think SSX fans don't know what they want. Yes, we're mostly split into two camps: Tricky diehards and SSX3 diehards, but the truth of the matter is that there hasn't been a good SSX game in almost 10 years. I'd say most of us just want SSX, in spirit, in hd: the high flying colors, the sense of speed, the characters and their personalities, the off the wall zany antics and tricks. Open-world, purely track, doesn't matter. I'd even say that SSX3 is the most popular game in the franchise, and most SSX3 fans, myself included, have only wanted a mere evolution on what SSX3 set out to do all those years ago. All I want is more.
But I'm a pretty open person and I'd be fine if SSX were just purely tracks again. Doesn't matter, at least I'd have more SSX.
I think it's overstated when saying fans don't know what they want, especially in regards to SSX, which is pretty damn simple. I'd even go as far as to say the people who don't like SSX3 due to the "open world" (it really isn't even that open) are a vocal minority. SSX3 was by far and away the most popular and well received game is the franchise and I think it's silly to lump all fans of a franchise under one bus thinking everyone thinks one specific way.
I think this game in its current incarnation looks really fucking good, even in alpha and I'm glad that they've changed the game to better suit something fans have been pining over for almost half a decade.
