I may have missed some of the details that would answer these questions but...
-Will this be only for skate park maps or will other styles work?
-What about a downhill racing mode?
-Are there any special surface properties that would be required for the maps?
-Would it be possible to tweak the pitch so that we could ride through a cork-screw?
I can think of more map ideas for this kind of mod than I'd ever have time to make BUT they would be mostly simple to create. I picture a lot of long, twisty downhill runs with nice "bobsled" type curves and tunnels and such.
This seems like a fun idea, I still have my old Fiber-Flex board (bright red, black grip-tape), my Solar Radiation wheels (neon yellow) and my Bennett Pro trucks (black and chrome) combo from the mid 1970's . I was ten or eleven when I first got into skating... I break too easily now so those are the days of foolish and carefree yore for me.
Speaking of skating, have you guys ever tried sk8, dbtrk1 or dbtrk3? The first is a skate park (where you blast each other with handcannons in AQ2, but would work in vanilla Q2 too) and dbtrk1/3 are racing maps. Do you know any other maps that make good use of the slick function to skate around?
