I have a simple question related to copyright of mods. The situation is as follows: there's a guy who made a partial, but already pretty good translation of civ5. There is a second guy who is not satisfied with some decisions guy no. 1 did and he also thinks he could translate faster as guy no. 1 might also work on other translation projects as well as he has private life. Now guy no. 1 claimed copyrights for his translation and the two guys do not have good relations to each other, so I'd say that no. 1 won't be happy if no. 2 starts an own translation based on no. 1s work (a translation is a huge work!). Now, I think I read that the creator of a mod (and a translation can be considered a mod) hands his copyright over to the games creator automatically, so no. 1 would not be allowed to claim copyrights anymore and no. 2 is fine from the legal status. Note that the creator of the original translation would still be no. 1, that status can't be handed over, yet this about the right of altering no. 1s work and re-release it giving credits also to no. 1. So what's the case here, is no. 2 allowed to make a fork of no. 1s work? I wasn't involved in this, I just have been told about it and I think I read that the copyright of a mod is handed over to firaxis automatically. If you can, please provide me documents that I can provide to the guys to clear the issue.
