Let me throw these questions for the OP:
1. Whats the significance of having this "creature"(ain't calling this a dino) in the game? Is it important to have this thing in the game?
2. Whats the purpose of this? Aside from being a personalized request?
3. Will the game lose a lot of relevance & JWE fan support if this "creature" is not included?
On to the section of Copyright
My third request for Clannfears failed. So now I'm asking for a hybrid that is not a Clannfear but looks like a Clannfear. This hybrid is a hybrid of Chasmosaurus, Microceratus and some random small carnivore species. The reason the it's part Chasmosaurus is because the Clannfears head and the Chasmosaurus' head are kind of similar.
So to avoid copyright infringement on Oblivion's Clannfear, you opted to go for the hybrid route. Even if you'd go for the hybrid route, you'd still hit the copyright barrier for 2 reasons.
1. You'd still be making something like a Clannfear, even if you claim its a hybrid, so copyright infringement. Unless you name it something else, w/c points to #2.
2. You got the problem of naming the "creature", if its not a Clannfear because its a hybrid, but looks like a Clannfear, whats "it" called then? Use of the name Clannfear is basically copyright as well.
3. Do you really think FD would hassle themselves with copyright issues against Bethesda just so you can have this "Clannfear" thing into the game?
