It still doesn't matter as we would never get on steam due to VALVe money making system. As long as we don't add anything like 5$ for 50k caps about which 2$ go to VALVe we can't get FOnline on Steam. Even if we do add such a feature (micro transactions) we get sued by Bethesda and get our asses fucked.
They don't though. They don't own fallout 1 or 2. Since when is it illegal to mod a game?
Fallout is theirs, we work with it's lore and all else. Also I've never wrote that it's illegal to mod a game. Though, if you check out the copyright statements in the original manuals (and probably where it's written elsewhere), there is written that you are not allowed to modify and release any files (which is something that every Fallout 2 modder has done by now, so it doesn't matter anyway. But it's still there).
I was mistaken about it being a mod, I was under the impression that since it used the critter.dat and master.dat it was, Because like all other fallout 2 mods, Those files are needed.
