We’ve received two Heroes 3 Restoration of Erathia maps from Alter Ego.

Gimme My Magic Arrow is a large single player map with the following description:

In times of the great human-elfish war, Aine decides to show the world what can be done with a little bit of magic. Unfortunately many nice spells are missing from her magic guilds, and she visits the Dragon Riders, hoping to learn some of their wisdom.
Things don't turn out so easy...

The second map, Crazyhouse is a medium sized single player map, though you have an AI ally on the map.

You are the head nurse of a large madhouse. Your mission is to tranquilize all the madmen before the National Mental Health Institutions Inspectors arrive in 4 months.
Schizophrenics are there to help you (although you wish they weren't).
Warning: contains some black humour.
