Vierstein is German for "Four Stone". The rules revolve around four elements, four attributes, and their combinations. Now with that out of the way...
This project is an attempt to make a RPG game creation and playing kit. In the spirit of games like Unlimited Adventures (FRUA) and, to a lesser extent, Neverwinter Nights, Vierstein lets anybody create a RPG game to be played by others.
I say 'spirit' of FRUA because the gameplay has evolved as I have discarded some ideas and changed others. FRUA is just the best example I have of an RPG creation program. Basically, I am shooting for a finished product over features.
The rules, for now, will be a static set of custom rules.
