Why do I always go back to Classic Traveller when I'm feeling down?
Is it because of nostalgia for the countless hours I spent in my youth designing spaceships and worlds?
Is it because of the inherent simplicity of the rules make it easy to run "thought scenarios"?
Or is it because in Traveller, the universe is truly what you make it, with the rules offering as much or as little direction as you desire?
I've all but given up on running an ongoing campaign at home or with friends, but on days like today, I still daydream about jumps into poorly mapped out systems, facing off against rival crews/gangs who heard the same rumors as you did about lost treasures and civilizations, suiting up in your best new gear in hopes that you're not bringing a knife to a gun fight, and doing 2d vector math while juggling limited computer processing resources.
Ok, maybe not so much that last one. :)
