I can’t research the “Better User Expreience” for my custom game engines, and since gamepad was moved to that in my realistic mind it means “NO CONSOLES OR PORTABLE CONSOLES BECAUSE THEY HAVE A CONTROLLER” which means im stuck to creating damn PC games
Better User Experience was there before they got rid of controller categories. Whenever you develop a game, imagine that it used the appropriate controller.
You unlock BUE by earning levels in Gameplay, IIRC, and by having already researched Engines.
