I played the map 10 years ago, and it was certainly a cut above the average user made map of the time. The map is extensively scripted and has been given a complex layout. There's a lot to critique as well though, on my first try I went north-east first and apparently triggered an action point that made an army of level 10 samurai and other heroes invade that was larger than my army of low level dragons and insects at the time. On a fresh attempt I went east instead and was never really challenged. As soon as I got a prison I could pick off the many small pockets of heroes and convert or skeleton them and even the large hero parties were never much of a problem. There was enough to do on the map that it never went boring though. What would be better is if the objective told me I had to defeat blue. Blue is your ally so this is not obvious at all. Also there are many things that suddenly happen trough the script that you don't know how/what or why. Many units have a max-level at first, but that stops at some point for example. I also got access to new research without knowing how I managed that.

This map is very chaotic. Many pockets of lava, water, or just spaces with neutral creatures, spells and other stuff. You have warning about heroes incoming but you have way too much time and you can safely train like 13 mistresses. If thats not enough to kill everything with help of some tanky creatures like dragons, you can make pretty much unlimited skeleton army. There is also Blue keeper which you are allied to, but heroes destroyed him pretty much instantly.
