But what about more specifik mechanics that are unique for certain games? Like in Hitman you can drag bodies, And use disguises. Or like in some games there´s a special cover system. Is there some patent or copyright involved or can anyone copy them for their own game?
Sounds Legit. You will be programming it all, right?
Imagine not being able to create a diablo-like inventory. Most things are a copy of a copy of a copy.
