Detailed descriptions? I'm unlikely to manage that, but I'll try to write something.
We started. Looked around. Took a hero, gave him 1 centaur, and he set off. We look at everything, including external dwellings (remember, cents are given for free; an elf external dwelling can lead to the formation of a decent strike stack as early as the second week), crypts, hives with cans, of course, and Dragon Utopias if you're lucky. A path leading somewhere beyond the mountains might lead to treasures or a secondary town.
Then it's time to release another hero, also with 1 centaur. We continue scouting.
Next, we take the main hero (Kirry, for example) and head somewhere. Where do we go? Well, that depends on the respawn. In an ideal scenario, you'd take three or four crypts that are standing right on the grass along the way to your own secondary town, but reality might be a bit different :)))
The first week should be dedicated to building up troops. Money needs to be taken from crypts, gathered in the field, and earned as income from the secondary town. There are also special buildings, like dwarf dwellings and other things. Here is how we do it: enter, they ask "want to fight?", we answer "nope," and then right-click to see who's inside. The methods for taking them are described in detail in a number of excellent articles, including on our forum.
If there's a can, after scouting its contents, it makes sense to consider how much we need the dwarves. I often used dwarves when taking cans; they are quite tough and frequently come with heroes. Those little dwarves that came with heroes are the ones I fed to the griffins.
The option with a Dragon Utopia on respawn in the absence of a unicorn external dwelling. Now, more experienced players will peck at me for this, but in this case, I prefer to try and put dendroids in the castle with a bonus on the first week (if possible), rather than unicorns in the Stronghold. I realize I'm probably not doing it quite right, but by the third week, you end up with a very serious number of dendroids. If you give them some magic too, like Blessing and Stone Skin, you might even be able to take the Dragon Utopia on the third week!!!!
Otherwise, it's desirable to put unicorns in the Stronghold on the first week, then those same ones in the Castle on the second + build up the secondary town. A unicorn external dwelling can help a lot, but don't forget that before you can hire unicorns for the first time, you'll have to fight them.
From there, play based on hero speed. An accelerated Kirry with fast troops is something serious.
