Ok, I have a specific question. I have read that you can patent in-game features, all kind of minor stuff, like an arrow on your screen showing you where to go, or the circle-dialogue menu in Mass Effects game (https://www.gamesradar.com/12-unbelievable-video-game-patents). My question is, when you try to patent something like this, do you have to provide an actual code, or you can just patent an idea? Can you just file an application saying "I have an idea of an arrow in top part of the screen showing where the player has to go, i want to patent it"? Will this be enough?
