Are the mods for skylines only on steam or are they hosted anywhere else for download?
Simtropolis is hosting some stuff. Steam Workshop needs some time for the popularity and rating filters to really kick in, but I do like just pressing one button and having mods installed and ready for the game. It's like the antithesis of the old SC4 dependencies-from-hell mess. Hopefully the off-steam mod sites stick to the simplest installations possible.
