Hi there. In most games, there is a splash screen with a logo before you start. I know how you do this, but if you were to make a name, such as BandB Games, does it need to be registered as a company with a trademark, or can you just put it into your game.
Hi, from my experience, you do not need to have a registered company to develop and publish a unity app or game, you can also be a sole trader, freelancer or just a individual testing the platform.
Although common sense would dictate that you own the company logo you put in the beginning of the App/Game, you can put anything on the splash screen.
You can disable the Made with Unity water mark if you buy the next packages after the free tier.(there is an option to disable it in player settings/Player/Splash Image and replace it with your own)
I hope this helps.
