"Original"

I've figured out how to create maps using the built-in map generator and templates. You select the map size, let's say a large one, and then a list of available templates for playing on that map appears. I generated a map using the 4z4k1m template with very strong creatures, and it turned out to be similar to the map I was talking about – a map divided into 4 equal squares. This template is quite playable. So, the built-in templates are definitely usable, but you need to plan ahead for the type of game you want to play. For example, if you're planning a fast rush, you can play on a medium or small map and choose a faction that suits that template.

It's generating a camp right next to the castle for me for the second time in a row; I'm buying two undead creatures in the first week for the second time in a row.

So, create maps with very strong creatures, and those 2 undead creatures will most likely help you, but only if you're playing as the Necromancer, and even then, maybe only at the very end. I've concluded that I'll only participate if the following is done: 1) the race for the game is chosen first, 2) the map size is chosen, 3) the template is chosen, and 4) the creature strength is set according to the map size (very strong for large, strong for medium, etc.)
