The old Space Princess came in at 48 pages with the table of contents, OGL and a page of character sheets (they fit four on a sheet, so I'm not sure character sheet is the right term). The back page is a map you can use for your first space fortress - I'm posting it below as well.
Lots of Space Princess ideas bubbling in my head today, so the next few weeks will see a few posts dedicated to it at The Land of Nod blog. I already want to do an expansion called Space Patrol that will get a little more into a setting, but also throw in some classes, monsters and rules that will make it more useful for depicting characters in a fleet that travels between stars, a "star fleet" one might call it, wearing technicolor uniforms, exploring strange, new worlds (maybe THE Strange New World), etc. etc. etc. You get the idea.
If you buy it, I hope you like it and get some use out of it - and if you come up with your own ideas and additions and post them, please let me know!
