I spend too much of my time thinking up naughty scene ideas. So here is another one!
I am going to steal the star wars level of space technology here, so stuff like hyperdrives, blasters, bounty hunters, droids, and so on. No Jedis. The basic story is that a country hunter ship filled with the crew (you guys), crash land on a undiscovered planet after someone missed a decimal point in the hyperdrive jump. Your ship lands more or less in one piece, but the hyperdrive is out and will take forever to for the droids to repair, which means wandering out onto the land to find food and provisions.
At this point you find the civilizations on this planet are in various animal-kinds. With the plains being controlled by zeebramorphs and the forest being in control of the tigers and so forth. With only one translator droid establishing communications and exploiting their primitive cultures for your own benefit will take a while.
So I would need players to play the crashed bounty hunter crew, along with others that want to play the natives if they want too. Also there is going to be a fun surprise for the newcomers to deal with, and give you something to shoot at.
Let's try this again!
