Colonization

The question for the author is: did he actually test the map with a hero? The thing is, even if you play optimally, without losing a single unit, and capture a Castle in the first week, by the end of the third week, you'll have a maximum of 109 archers ((13+12)*3+7*3+13), 66 swordsmen ((10+12)*3), 32 peasants ((22*3)-(7*3+13)), taking into account that they are converted into archers, and three knights. Even after destroying all the monsters in the surrounding area, the hero only reaches level 7. Your spell arsenal consists only of "Surveillance," "Haste," "Slow," "Mines," and "Magic Arrow," which you get after defeating the griffins (which, by the way, you can't do without losses – at best, you'll lose 5 peasants). These forces are clearly not enough to defeat the Necromancer with 250 skeleton archers, 30 specters, 4 Death Knights, and a hundred zombies, especially since he knows "Raise Dead" and has 70 mana points. If the Castle could be upgraded to a Stronghold or a new Castle could be built, or at least archers could be converted into ranged attackers, there would be some chance of winning. But as it is, even if you manage to destroy the enemy's catapult before it breaks through the walls and cut off the infantry, the constantly resurrected specters and skeleton archers will wipe out your entire army. Of course, there's the idea of not taking a Castle for a couple of months, until you've amassed several hundred archers and swordsmen, but that's not very logical or interesting.
