Unity actually gives any class with the name GameManager a special gear icon. You cant just forgo the cool gear icon!
(Its not too terrible from an organizational standpoint because most of the scripts are attached to game objects. MonoBehavior is a component of GameObject. For instance, you’d never have player movement in the GameManager class, you would put it in the component class attached to the player character GameObject.)
I believe it. A friend of mine raised the price of his game from free to $2 with a big update, and still kept the download for the older version free. He got all sorts of backlash, even death threats. These people are children.
