What has been outlined based on the information so far is that AC provides a platform for the game to its users, where race organizers and 3D modellers can freely implement their diverse ideas.
While in AC EVO, I have the feeling that you want to lead the entire community, but in doing so you limit the tools of the experts. Or will there be shady areas where we can achieve the freedom of AC? In such a case, users would receive a warning that the vehicle data does not correspond to reality, which may have completely unexpected and unrealistic properties.
For example:
One of our members regularly makes completely unique cars for the Christmas season by modifying an existing one. Adding light strings, Christmas tree, driver animations, etc.
As an organizer, can I throw out my soapbox race, where the competitors had to start with their own 3D model?
Same for tracks. I had to modify them more than once. I had to add more slots, prevent cuts, create unique lines, etc.
Last questions:
Are you planning microtransactions?
