Yeah, I was wondering if Bethesda did anything about that game that used their meshes and textures, and if so, (what did they do?).
You're probably thinking of
Limbo of the Lost, which used screenshots from many games to make the backgrounds. It was pulled from the shelves and is no longer being sold. I don't know if additional legal action was taken.
how close to a theme can you get before copywrite infringements take place? (like you said, would you just look for Enclave, super mutants, etc. ; similar quests or characters, etc. ; or similar meshes and textures like that one game did with Oblivion? I was just wondering how games handle that.
I'm not a lawyer but I'm pretty sure you have to be very similar before it's considered infringement (parody can get away with more, but that's not a factor here)
Let's use ghouls as an example. They're very common in post-apocalyptic settings, sometimes as actual undead and sometimes as irritated husks. A game could include things like ghouls, and even call them ghouls, and I doubt Bethesda would care - it's a PA staple. Now, if those ghouls live in a museum of natural history, particularly an old exhibit about death and the underworld, that might be infringement. By itself it may not be enough for legal action, but if there's also a grounded aircraft carrier called Bolt City, and a city called Warhead built around an unexploded missile . . . .
I seriously, seriously doubt that Wasteland would copy things so closely and I'm sure they wouldn't use actual art resources. They're a professional developer and they know not to commit obvious theft. In fact in general I think the concern that a Wasteland game might infringe on Fallout is unfounded. The games may have very similar themes, but there's nothing wrong with that.
