I have been looking up the laws of copyright for games. A lot of the stuff you find is pretty vague so it can be extremely difficult to have a good understanding of what you can/can't do. There are a range of different styles things can be done in, so how would it be determined if something is "too similar" and therefore infringes copyright.
This came into thought while looking at "Zelda - A link to the past". The game itself is very basic in design, 2D low resolution textures etc. If this were to be remade in 3D which would look completely different to the original style, could it still be considered too close? Does this account for storyline too, can you copy that?
I read this in another post:
Copyright will protect only the computer program in the form written by a programmer i.e. its source code. Neither the functionality of a computer program, nor the programming language or the format of data files used in a computer program in order to exploit certain of its functions constitute a form of expression of that program, and thus, those are not protected by copyright
So is storyline considered functionality and therefore exempt? It's too vague and is quite intimidating, any information on this subject would be interesting.
Keep in mind, I am not looking for advice but rather a broader understanding of such a vague concept.
