Haha, thanks for the laugh, guys.
Goa, yeah, I hadn't even thought about age of the map not working. What prompted me to search for and ask about it, though, was that I had started doing research into the various planets, planning on making a solar system map myself. While doing the research and trying to figure out how to handle a few things (grav well <-> planet/moon distances, some moon classifications, etc), it dawned on me that someone must've done this before (dunno why I didn't think someone had previously...). Oddly enough, doing a quick search on "solar system" seemed to only net me that thread that I saw, but eh. I figured at the least seeing how someone else did their solar system would help me figure out better how I was gonna do mine.
I'll take a look at Infinite Space's, though. Thanks.
