I am basically done with StarCluster 4 - Dark Orbital. I will start playtesting it this weekend. You can play this game two ways, I think. Most people will probably play this all grimdark. I - on the other hand - will be running this as black comedy. I personally really dislike grimdark, but it's apparently very popular, while comedy of any kind is really unpopular for RPGs. So, my advice: If you find yourself somehow tricked into running this thing, because I'm sure that's the only way anyone is going to run it, remember to put away your sense of humor first!
