Blasters and Chrome is a shameless Space Opera. It doesn't make Carl Sagan proud, but it should be fun. I'm going with most appropriate sci-fi tropes with technology being a bit higher than Star Wars. No FTL, though. Interplanetary travel is handled exclusively through jumpgates called "Arks". This espouses the idea that no matter how far technology advances, humans will still be human and do human things in human ways. See the houserules section for specifics of technology.
Most shows and sci-fi properties assume that space travel and alien contact will be handled by governments. Government ships do the exploration, diplomats negotiate treaties, generals wage war etc. In this game, at least, this is totally wrong. Governments are content to be insular and manage their own worlds. Militaries prepare endlessly for invasion.
It is the entrepreneur, the independent contractors that venture out and make first contacts, that dare the reaches of the dark and risk life and limb to push back the veil. There is no safety net, no security forces and no police to run to if they open a Pandora's Box.
