The importance of water on the map.

Once, on a random map, the AI-controlled Barbarian was surrounded by mountains.
Luckily, I had a teleport spell.

I also don't like water, but sometimes I want some variety.

By the way, I had a similar situation on an online battle random map, where the AI-controlled Swamp was surrounded by mountains, and there were no necessary spells, only a small piece of land with 2 mines. And it was only possible to teleport into it from the outside in one place, and only for 1 square, but I had a huge space for development. :) Of course, this is not about water, i.e., it's off-topic... :o
