I got the new issue of egm magazine with SSX: Deadly Descents on the cover. Reading the article, the developers say one of their main inspirations is Trials HD!
quote "On a next-gen platform, snowboarding down a mountain, could create a core gameplay experience that was essentially Trials HD in three dimensions?"
Yeup i played all the SSX games, Tricky was my fav. I remember playin on that pipe dream level over and over and another level where you had this huge *** jump to rack up points.
