                            BODGERS is the more widely known Glorathan implementation of this. It plays like RuneQuest (with very easy conversion between the two systems), but it is simpler and plays faster.

CARDS RPG  :
                            This is a simple impromptu RPG system made for gamers on the move. It took me 32 minutes to design, so the rules should be relatively straight- forward and easy to remember. All you really need is a good game master, some bored gamers and a pack of ordinary playing cards. Nothing else.
