Would be dope to have all mods on steam workshop, so players could easily subscribe to a mod and have steam add it. Would be beneficial for mod updates, so that players won't have to search forums for a updated link. Steam would update the mod automatically. Idk what goes into something like that, but it's dope.
I consider this the most important thing to implement after connection issues are fixed. It would boost sales and ease of use a LOT! If workshop was used, we wouldn't have to deal with incompatibility/missing bikes problems and selectively have what we want on our storage space.
