Several times, just for fun, I played on a 200% random difficulty on an S-map without a Dungeon.
It will be more difficult with a Dungeon ;), but with this setup, you can destroy 3-4 computer opponents on the first day!
Imagine, your Castle is located on the central island,
and starting from the 2nd week, computer opponents start attacking you from all islands.
But what an adrenaline rush... :) - sometimes it can be fun...
And I won these maps, under the condition that the Castle can only be reached by water (without portals).
Interesting, how? ;)
Well, it happened to me too... ;)
