“Design is more than meets the eye … The purpose of design is to communicate an idea. It is as much, if not more, about function as it is about looks. It is as much intellectual and visceral as it is visual. If you don’t have a clear, well designed message, you don’t have a design. Design is marketing, marketing is design”
The purpose of game design is to provide an enjoyable experience. Focus on a clear defined core experience as a base.
“Design is about communicating benefits… No matter what you’re selling or giving away, if I am your prospect, I want to know what’s in it for me. I have hard-earned money or time to invest and I rarely part with either without the promise of some return. Are you going to entertain me? Educate me? Inspire me? Solve my problems?”
Is the core experience something that players want, will identify and enjoy?
“Design is not about designers … The good designer pleads “Create a design that answers your client’s needs.” The bad designer commands “Don’t be an idiot—design something that’ll look good in your portfolio.”
You are rarely, if ever be the target audience. Understand what the experience your audience will appreciate.
“Design is not an ocean it’s a fishbowl … Design and marketing ideas are not always interchangeable—be careful about the principles you apply and how you apply them.
High concepts and designs are not the same thing.
“Design is creating something you believe in … The saying goes something like this: “great advertising will kill a poor product faster than no advertising at all.” The same is true with design—good design will attract an audience faster than poor design. …Step away rather than compromise your values.”
Form over function leads to shallow experiences, function without engaging form is a dry game. Good function is the bedrock of game design.
