Now this isn't a game but I still wanted to show you guys. I made this on January 10th and 15th. My teacher game me a project for Geology to make a powerpoint and I realized I don't have it on my computer so I chose to do it my way <img src="smileys/smiley4.gif" border="0" align="middle"> I put about 9 hours of work into this (About 1 1/2 of that being research and almost 2 of it actually playing games) I got some MUCH appreciated help from 
DravenX with the tectonic plate borders.

Now I just hope my teacher likes it enough that I'll finally be passing Science!
(The starry background, asteroid, cursors, and tectonic plate map are not mine. Everything else is)
