I already posted this on the FB page (with a picture), but a crazy Belgian told me to repost it here.
In Rollcage, cars can drive topside upwards, and flipped over topside downwards.
Now, if you put a small icon (a yingyang ball, or whatever) on the player's HUD or give cars two paint jobs (For example, top red blue bottom), then you could connect this to my gameplay idea;
In the game (or merely in one gameplay mod) put racetracks with minefields (or revolving doors, or whatever), which can be traversed ONLY if your car is currently driving topdown. So, for example, if your topside down car drives over the mines, they do not explode. If your roof-up car drives over the mines, it explodes. This gives players an incentive to use the tunnel walls to flip their cars. + it produces shortcuts in your racetracks which can only be used under certain circumstances.
