Like I am sure countless others have already said in a reply. Micro transactions if done right are not a bad idea. Nothing that breaks a game just keep it simple, shaders skins, ect. Nothing that you kind of actually need to play the game and nothing that gives people any advantages over others. Make it things you can only get via purchase not in game, that way people who earned something actually earned it . Micro transactions are a good way to support a developer so they have money to keep adding content and improving our game.
