1. The limited space forces players to explore.
2. The guard and the initial armies on the map have 665 hit points (I took the average =)).
3. Buildings are too easy to acquire.
4. External outposts – I paid tribute to the second game; if you tie them to the map, it's also too easy.
5. Buildings with resource battles – there's an abundance of resources on the map, and there are already enough mines and scattered resources (I played the first test – there were resources everywhere, I built magic structures wherever I could).
By the way, the scarcity of high-level artifacts was also intentional, so that players would genuinely be happy when they capture them.
