We just need a skateboarding simulator. Or better a scootering simulator. Another stuff that would boost up realism would be:
1.Breaking stuff.
2.Spin physics (backflips, 360s) in a way of a key/combination which loads a bar when pressed before jumping, the longer you press, the faster will the rider spin; this way you woulndt be able to stop spinnin in midair and you could vary the spin speed depending on what you're doing, like you spin a 180 down a big set slower than a 720 over a boxjump.
3.An option of a real injury and death mode, like in roguelike games; these are text mode RPGs, you only have one slot to save the game and you can save it only when quitting the game, if your character dies the save data is deleted.
4.NO AIRING QUATERPIPES THE STIFF WAY, the position you lean in when riding into the pipe would depend if youre gona air it, jump into a stall or do a flyout.
Constructive criticism rules.
