Heroes 5.5 WarGame Edition - Tactical Edition.

Actually, the balance of the original game is designed for a maximum of two months of gameplay, while here, the maximum is one month. This is to allow players to complete an entire game in one evening (2-3 hours). And to prevent the game from dragging on to the point where cities are fully built, and there is nothing left to do on the map.
As I mentioned before, it's pointless to try the mod on full-sized maps right now because:
1) maps need to be adapted to the new dynamics.
2) a complete version of the mod is needed (currently, only the duel format is ready).
