Hi, guys, thanks!
Tarkh, you are exactly right. I asked Jim Shepard for advice, and he told me this: "what burns in your heart that you think other devs need to hear?"
And the thing that satisfies both those criteria is "Infinite Gameplay". It was obvious... In hindsight!
Future features... you can get that here. You can also influence it
Thanks again, got more planning to do...
