Necropolis or Castle (Which one is stronger?)

If it’s a random map, then everything depends on His Majesty, the Map Generator :D. On average, in most cases, the larger the map, the better the chances for the Necromancer due to the skeletons. But! this doesn’t apply to all large maps! Similarly, it can generate a large number of griffons, and then the Necromancer with his 1-1.5k skeletons by week 4-5 will have a very bad time against approximately 20 archangels. In addition, the Humans will have the advantage of the first turn, and if you play as the hero Turis (specializing in horses, with the Tactics skill), you can use horses to “stick” liches, dealing bonus damage of about 60-70% of their attack, and then nothing will prevent the Humans from clustering together, protecting the archers. Then the Necromancer’s song is over, because the vampires will be defeated in 2 turns by the archangels forever)). And on top of the vampire corpses (which are probably double corpses by now, because even when they are alive, they are still considered dead :D), some halberdiers will appear, and then no one will be resurrected anymore. So, it still depends on the player’s skill.
