Players will therefore be able to download and upload their creations via Steam Workshop, in the same way as for vehicles.
By launching Steam, you will therefore find 2 updates: one for the game, and one for its publisher. I don't think that potentially copyrighted content included in either of the games has anything to do with it. This information is freely available online (US Patent & Trademark Office), so I don't think there'll be a problem posting it here.
