You can also ask player to subscribe to the same mods (if its a steam workshop) - it should work as well
It really doesn't. Trust me on this one.
They take a while to download for most people and takes even longer to install properly (especially the maps and stuff for the GM games).
It will work, but no one wants to wait for hours for it to work.
I made a game with 15 different mods, totalling 800 mb and it would take ages to download for people.
