We have a Heavily updated version of Iron Heroes and I am working on building a new game system based on this. We have 3 players in the group but one or two more would be perfect.
The System is posted here:
It has a lot of potential and it is heavily aimed for Skill use and Role Playing. The Spell system is still under construction and I am working to make it fun while falling inline with the rest of the system. (the original system punished the players for doing magic. this system just tries to balance it out.)
