Rough draft. idea.
Two players per clan, All other run Comstar against those players.
Use Planetary empires map. Set up map, with certain tiles having scenarios based upon the Tukayyid sourcebook.
Each Clan must take their two designated cities.
Add stats and rules for Royal mechs.
Maybe two games at once.
No Infantry for Comstar. Clanners limited to a max of two stars of elementals, and elementals can never outnumber mechs.
