Private/Public Custom Lobbies should be available for anyone to create and customise . There should be a separate menu system that allows players to search for a Lobby that they might want to play in (infected A class, street race B class…. ect). The player that creates the lobby should also have the ability to control factors about the game itself such as weather and time of day. (Racing used for example for other game modes would be similar). But also, they should be able to choose if the Lobby is:
Ghosts (on/off),
the car class,
car type,
max hp/min hp,
AWD,FWD,RWD/ a mix between them,
Race finish timer,
Street Race,
Road Race,
Cross Country,
Mixed,
Team Race,
The list goes on.
The creator of the lobby should also have the right to kick players they want, decide the teams (this would be great for club race wars). They should be able to make it a spec lobby (everyone drives the same car or everybody drives the lobby leader’s car +tune).
Overall there’s so much potential to do anything with these lobbies and it will help with the longevity and life of the game.
