May be exploring and building part will be like in Heroes of M&M, with several heroes exploring the map, gathering resources, finding some relics and such, and it is be turn-based. Battles may be like in Medieval 2 TW, real-time ground (castle defenses and land units with some air support) against air assaults, and air battles only (zeps and dragons against flying fortresses), depending against who we fight (other armies, some wild tribes, or attack castles).
