Acomba MikeBeast of War, what it is is not a copyright, but that it would be stealing to take RtR or SW models (that you have to pay for) and then use them in a mod that only requires BF to run. This is because that way, someone could just release the whole of SW on the internet as a mod, for free. You can only mod what everyone has: and not everyone has SW. The only way they could use those models legally would be to make the mod compatable only with SW, so everyone who plays it has already paid for it.
You can mod BF because we all own BF. You can't include SW or RtR models unless everyone playing it has SW and RtR as well, otherwise it's theft. That's why it's not allowed.
EA have forbidden them to use stuff from RTR... Funny that they don't complain about the music though, seeing how Michael Giacchino is a freelancing musician also, doubt he would appreciate it.
