Great battle as always is Naran the system you're using or the name for your setting?
We use a set of rules named "NARAN FUTURE WARS", a sci-fi version of the well-known wargame
Fantasy Warriors - former Grenadier - which is now being distributed free of charge by the Italian company Mirliton and by the English EM4, which are held on the property. By the time we have an excellent relationship with Mirliton, and from it we had permission to put in our site an our variant of Fantasy Warriors, "NARAN FANTASY WARS" in which we have included also some of the changes suggested in the forum of Frothers.
The name Naran: we have invented it for the fantasy world that formed the background to Naran Fantasy Wars, then we have expanded it to a galaxy for the futuristic version. See our site
