I think this would be a great idea for a role playing game, play by post.
I have seen the rule book, the core stats use four six sided dice, added to 48. Stats, like strength, health, agility etc.
Entering the game, as a colonial marine, fighting aliens. But, not every mission being a "Bug hunt," maybe its exploration, espionage? Or a rescue?
I think it would be a novel idea, creating a world where characters, create their own story. It could be a recon, military takeover, peacekeeping, investigation, civil order.
We are all familiar with the Alien movies, but that's only a glimpse of their world.
If there would be enough interest, I don't think it would be to hard to game master it. There is enough information available to create a character. Plus a world to interract in, and create.
