http://www.3dgamestudio.com/download.phptry out the tutorial section (like the lite-c workshop, it should be a good starting point for scripting)
there's also other links on that page
like this one which says it has a few free videos:
http://www.create3dgames.com/gsbasics.htmlhaven't seen it myself though
maybe even 'first step' on this one?
http://lion-ts.com/modules.php?name=Tutorialslooks like it covers the basics of making a simple game
well that should get you started
welcome to gamestudio, have fun, and don't get too annoyed at any bugs you will accidentally make : )
