just a tidbit from my "space pw"
I've implemented a space system already with working navigation computers (autopilot) or in manual mode (shows a topdown using a controllable sprite with planetary collision system etc. IE: Run into a star, you die

BTW stars already give off light effects $$ =P)
Its not lame like the others, especially with all the "perfecto" custom graalian space graphics and tiles. (secrets secrets)
