Rpggame is a project mainly written in Ruby, it's free.
An attempt to learn about classes and inheritance in Ruby.
Attempt to mess with Class and inheritance, this is a very basic random character generator for a role playing game, probably targeted on OSRIC (aka wink-wink AD&D 1st ed: http://www.knights-n-knaves.com/osric/)
Things to do:
Make a Class character with attributes (Strength, Endurance, Dexterity, Intelligence, Wisdom, Charisma), an array with alignments, an array with races and an array with classes. Maybe top it off with a string for description.
After the class is solid and you can generate new characters by using a method, work out some way to randomly generate each stat. And for extra sugar, have it all write out to a text file! Badass!
