That version, along with Zup's, is completely functional. It includes leveling up, skill, move, armor, and special abilities/SD thereby combining the best ideas from Zup's and Silva's. It is the most comprehensive one on the forum.
It is also impractical, as leveling up takes a shitton amount of time (aka multiple games) although since I reduced the number of levels it may have gotten a bit better. If we wanted to introduce this on Eurobricks we would want it to be different from the Heroica thing- maybe the distinguishing feature could be a focus on the combat instead of role play? You would also have to contact Dragonator before doing anything, and the battefield should be decently constructed and the violence handled in a professional manner.
EDIT: I'm going to go back and rethink my brikwaRPG system. I want to account for unit cp somehow and have an XP system to make the leveling up mechanic better, but that might turn off actual brikwarriors due to the math involved.
