I've had 2 great ideas for CSS fun maps, but I can't make them because Valve don't want to make correct things.
First, why didn't they put the vehicle/buggy code into CSS to allow custom mappers to have a lot more of possibilities?
2nd, why can't you see yourself on 3rd view?.
I wanted to make mario kart race maps controlling Gman into the buggy, father Grigori into a driveable bath, Gordon Freeman riding a Combine Advisor, etc etc. And I can't because physics mess up the vehicles.
And as a secondary idea, I've had the idea of making LittleBigPlanet cooperation maps, but when I set the point_viewcontrol camera I can't see myself. Any fix? I think no.
