I'm pushing everything down lately. Down to Group Level. I'm refusing to develop a setting for StarCluster 3E, and instead giving the group tools to develop its own Cluster. Random generation is fine, but I expect some of the uses of the tables will be choosing as if from a list, whether entirely or partially. That's cool. I really don't care. StarCluster has always been fairly firm. Now it will be as firm as the group cares to keep it. If the group wants to totally ignore science, that's fine - the game supports it. If the group wants to make it harder, that's cool too - the game will support that as well, so long as you make the effort. Need an alien race? Create one! Here's a tool to do this. Want to create a planet that's a hell hole except for one place? Do that! Here are tools to define it. Here's how to make it work for you. Want transhumanism front and center? Go for it. Here's some tools.
The point is that setting need not be a case of the all-knowing designer dictating to the masses how to run their games. Not my will but thy will be done. You, the group who is going to play this game, are the only ones that matter. Luckily, I enjoy making tools, and I enjoy hearing what creative uses people put those tools to. I'm pushing it all down to you, the group, to play with however you want. Go for it!
