I think it will be interesting to give some “passive income” to Workshop map makers.
Imagine - Every time a map maker logs into the game, a pop up shows up which reads “during the last XX hours, your maps have been played YY times, thus you gained ZZ points. [Map-by-Map Breakdown]”. The actual rewarded amount doesn’t need to be (nor should be) substantial at all. For example, 1 unit for each game hosted on your map would be sufficient. The point of this system is to provide some dopamine to map makers so they are encouraged to make more maps.
