Game designers, for an article I'm writing: What are your golden rules of game design? Full credit will be given!

In the bunch of direct tweets that followed, I asked them to share one tip they would like all other designers to take note of. Some designers responded through tweets, and some through direct messages, so pardon the unusual formatting that follows.
I was going to write a more in-depth piece, going over each issue, in a similar way to my Game Design Deadly Sins article from a couple of weeks back, but honestly, many of these designers say it better than I ever could! So here are their responses, in no particular order.
