I think the gear weren't upgraded to match GURPS 4e. Tech Levels were changed and the 3e rule allowing for improving beam weapons and armor was done away.
Anyway, I offer my services as a GURPS head if you need me. If not, I will be cheering from the sidelines.
I told Jean she needed to set aside revisions of existing books and get new RPG systems done, but she made the case (the cherry pie helped me accept it) that she could not tell someone to "convert this to your system" if "this" was a botched GURPS chart. So I said she could go ahead and fix GURPS.
