Trickster gave me this http://www.ruby-doc.org/core/ when I showed an interest in learning Ruby.

RGSS is Ruby but with prebuilt classes and such. Basically they take all the really hard code you need to write from scratch and do it for you - any new scripts would mainly be modifiers.

http://www.creationasylum.net/index.php?showforum=135 has a bunch of tutorials specifically for RGSS. Just remember you need to know Ruby to write RGSS effectively.

We might be able to use some already made scripts, it really depends on how complicated we want to make this. If we go with the top down ABS idea, then you really don't need to learn anything.
