Quoted from ArcadiusMaximus:
So what's the verdict on GB mods now? Things seemed to be pretty strict at the start, but now I'm seeing all sorts of mods with logos and characters from the film.
I understand the characters and logos and what, but how is the fire house and library off limits? The are existing buildings. Not like Columbia pictures built them as part of a set. Can anyone clarify this?
Selling anything with a logo on it that isn’t licensed is illegal. If you copy something that’s licensed, that’s illegal. If you modify a licensed product and sell it, that is legal.
