well not for RimWorld
Download from the steam workshop with
http://steamworkshopdownloader.com works nicely. One can also download direly using a
Userscript like this
https://greasyfork.org/en/users/6073-sean-campbell.
But it only works for games were download from the steam workshop have not been disabled. Or perhaps rather been enabled.
Like in don't starve or don't starve together. So Klei Entertainment did enable download thus completely supporting users using a DRM free version. Ludeon have apparently not done this entirely.
Notice that workshop-download works for don't starve together and I think that game is newer than RimWorld. --------------------
Best bet is to look in forums or nexus.
now there is way to get downloads from the workshop but this require use of sites that keeps copies of workshop-mods around for downloaded. So if you feel lockey you can find mods there:
1)
http://catalogue.smods.ru/ Works relatively good for games it support. Also it will tell you the date a mod was fetched. to use click on "
How To Install Mods" then enter steam id of mod you want in the field right under "SEARCH BY TITLE OR STEAM ID" left side.
2)
http://steamworkshop.download/ looks and behave as if it download direct from the steam workshop. But it works using a database. Mods downloaded tends to be really outdated. No proper info is given of how old it actually is. so only use as a last try.
Me i stay with
Dwarf Fortress until one can download from the workshop like from don't starve. or other unblocked titles.
I stopped entirely using steam a long time ago after being fed up with the DRM (Digital Right Minimization) there.
