Sorry for the self-promotion, but I created a way for S.T.A.L.K.E.R. mods to be distributed through the Steam Workshop. I am just trying to get some feedback and see if this is something I should keep working on:
S.T.A.L.K.E.R. Mod Player on Greenlight
The idea is that you can browse different mods on Steam and select ones you want to install. The mod player cleanly adds and removes mods, so you never have to mess around with zip files, configuration files, etc:
If this is something you think would be useful, please leave a comment on the Greenlight concept page. I'm going to use the feedback to decide whether to finish this project. Thanks.
