I have long used two other gaming systems to run 2300 AD. A long time ago I started using the "Hero" system and at some point jumped to Fuzion.
Both systems are good and I will eventually paste all of my notes here how to convert between systems and such. I am going to kick things off with Fuzion since that is how I like run any pbems within the 2300 AD Universe
A LONG time ago Matthew Pook and Søren Petersen gave me permission to host their GURPS conversion because the original website was going away. I am not sure if they ever got it back up, so I present it here, with permission once again.
