Legal question

[jdunehew]

If I wanted to make a companion app for a major release of a game (example, Minecraft, or Battlefield etc..), how hard is it to find out legally what is possible that I can do?

I normally would assume "lawyer up" but there has to be processes already in place I would assume by companies that release major games like that?

Might wanna delete this and post it in the business legal forum you will get more responses.
