The title says it all.
It is not like the size of 50ish mb.
The biggest map of Sins of solar empire is merely less than 500kb, others are much smaller.
Even ancient system like battlenet (1998) has this feature.
Most of FPS, in which the size of map is about 20mb, have this feature.
Currently there is no multiplay with custom maps because people just do not want to close game, open browser, look for the map and download it into correct folder.
