If you already know how you’re going to play (right or wrong, good or bad) then having a system that tells you how to play may not be what you want.

These days I sometimes know how I’m going to play and sometimes don’t. And most of the time, all things being equal, I want someone else to do the heavy lifting for me. So designers, fill your damn boots.

But still and all, if you can give me a setting that fills  me full of cool visions and ideas, you may tempt me into doing the lifting myself.
