We ♥️ Cypher System!

I humbly request you add a lonely star at busywyvern.com

Oh! Or Stars without Number with some tactical beef bolted on would be pretty good!

You'll have to look for more rules heavy systems. At that point you might want to use a D&D 4e scifi offshoot.

Conspiracy -X is mentioned but isn't rules light. Stargate SG-1 is also said to work, but may not be rules light.

I feel you could get there with something like a Shadowdark in Space offshoot, of which there are a couple. But if you really want the tactical experience...

Be the change you want to see in the world!

But seriously I feel like I've seen one but can't remember. I'll ponder.
