First- thanks for doing this. I've never really played all the FOC content because I have dealing with Consortium. Does this work with GOG? I bought it through GOG, and have subscribed but it keeps telling me I need to buy DLC. Thanks

Hi! This version of the mod is only available for the Steam Gold Pack edition of the game. The Steam Workshop only allows you to play the mods with a game on Steam.

To play UGC CE on another platform, you can download the mod here :

It should be more or less compatible. Be aware that the Steam version is the only one being updated by the developers, so if you're a regular player, it might be worth looking into buying the game on Steam.

Have fun! :-)
