I recently made a simulation game like Gamedev Tycoon where you are in charge of a game company and planning to release it on app stores soon.
I have few questions about trademark and copyright laws, as in game there are different companies (competitor) who release games, make sequels to previous games, release consoles etc. I know that under parody law I can change a company name from MICROSOFT to MICROCRAFT or MINORCRAFT etc. But what if I provide users an editor where they can change company names (if they want to) from MICROCRAFT to MICROSOFT?
Do changes made by players with my editor violate any copyright or trademark law? How can I handle that?
