body: I'm willing to remake an old video game, first as a hobby project, but in the future I'd like to publish it online, for free or as a commercial project.
  
  
  I've been reading for a while about copyright infringement, and despite not copying any artistic assets, lore, names, or things like that, I'm afraid I could run into copyright infringement.
  
  
  The reason why I think so, is because I would be using some very specific mechanics that are key to the gameplay, and I suspect those mechanics can be subject of copyright.
  
  
  Without entering into much detail, are there any kind of rules that apply to gameplay or game mechanics regarding copyright?
