Why can't we just have a "Chinese menu" (one from Column A, one from Column B, etc.) system? If I want to race a 14-liter Fiat Mephistopheles against an AI-driven 125cc Go-Kart and a fellow human in a hopped-up Porsche 917K at Monaco under the lights to see who wins after 24 hours, WHY CAN'T I?
There are 2 things from the Race series that would be nice to have in rF2: 1. The car filter system. Lets you create your own "class" of cars by combining any of the cars available. 2. The ability to create custom championships without the need of a 3rd party app. The Race series gives you complete freedom to create championships with any tracks and any cars.
Currently you can, but you have to make the playlist (.rfmod) for it, to ensure everyone coming to the server has everything needed. If the Race type filter system could be made into a sort of dynamic .rfmod where you can choose the wanted packages (cars & tracks) in-game, that would solve many problems.
