Originally started in 2002, Chaotic Playgrounds is described as a "pseudo-random map" that includes some of the most complex scripting ever seen in Heroes of Might and Magic IV. Thunder (Humakt in the forums) allows you to control the map size, the number of computer players, the number of heroes, the difficulty level and how rich in resources the map is. The map offers a good amount of replayability and a challenging AI: "I even had to abandon my towns to it in order to survive," admits the mapmaker. Please note that the Equilibris mod is required. You can find more of Thunder's excellent work at Thundermaps.

Cyntefyn has been hard at work too with a pair of Hammers of Fate maps for Heroes V. Both Pathways and War Grounds are small 1-on-1 maps with underground that you can play against a friend or a computer opponent. I'd really feel like playing a hot seat game right now.
