There's a board game that I really like called Mystery Mansion.
I want to make a similar digital version of the game for various mobile platforms, but I don't want to get sued by Milton Bradley (Now Hasbro) for infringing on their idea.
My game of course would not steal any of their artwork and my gameplay is slightly different, but the core of the game uses the same mechanics of a modular game board.
Is changing the artwork enough to avoid infringement?
I heard through the grape vine that game mechanics can't be patentable but the layout of the game can (Scrabble for example patented the layout of their game board, but not the Crossword Puzzle gameplay, or so I've heard). Is this a true statement?
