I thought about ideas of adding mode for quick battles (skirmish battles).
Its for distant future, I think.
It’s like it was in “Conqueror: A.D. 1086” game.
When going to menu of skirmish battles, player can choose to load battle from json config file (from mods or VCMI config folder) or to create random battle pointing size of army in hit points for him and AI).
When player presses start, skirmish battle immediately starts.
PS In JSON configs modder can set starting army of heroes, or set up hero, his spells and skills. There should be possibility to play against hot seat human.
