For first thing I'm thinking of using The Free State as a setting. It's a libertarian amalgamation of races, companies, ideals all held together by common purpose and philosophy. The intrigue could take a number of forms. One I'm thinking of is corporate warfare with us playing mercs, spies etc. I have a decent plot worked out that I think could extend into a really fleshed out RP. I'm aiming for equal parts suspense, action and of course humour.
