I love the 'different eras' idea. It'd be great to even switch trick sets dependent on era. Proper boards, clothes & wheels etc. And if they get pros in there, do a full motion capture with their style & trick selection, especially if they get the older dudes in. True physics that change with board set up.
A board customiser would be sick too, so you can change the shape & geometry to whatever you want & it all changes how the game plays. Would love to do a vert run on a polariser.
And a huge open world with hillbombs that count.
And fucken SLAPPIES.
Theyve got the resources, so I hope they do it right.
