When I develop a new game how should the levels for every part should be at the 3 stages of development?
For example at the last stage with World Design , Sound and Graphic if I max all 3 its wrong ? How should they be splited?
It depends on the type of game you are making. For example World Design is much more important in RPG’s than Graphics or Sound, where action games tend to be mainly Graphics focused, World Design being pretty much not required.
Try to think of real games and how much each slider has as an influence in them games, it should give you a rough idea on where you are going
