It's an idea I got after browsing some old RPG material.
In one of my game, I have a world hex map. The map is simply rectangular with an hex at the top and the bottom for the north and south pole.
But there is another kind of map which could be interesting but I wonder if it would be actually easy to play with. They are called
Isocahedral hex maps
Here is some samples I found on the next
(I can't find a way to place then directly in the post, so you'll have to click on the link).
In a board game, maps like these can easily be created using a hex map spreaded across the triangles. Here is a template map I could use.
Now How playable is this map is?
First problem, there are half hex. So the egde of the triangles of the top and bottom emisphere should be made of water to make sure they match what ever the terrain. Problem, if units can move on sea hex, it becomes unclear where you are.
Second problem: It might not be very clear to visualise where you are and where you can move ( for the top and bottom emisphere). Sure you just move the hex across, but not sure if it would be that easy to play. If land are connected over these hex, it might not be obvious.
Third problem: Can it be made as a modular map? Using triangles like this makes me think about gheos. In gheos, the land cover the whole side of the triangle. For my design, I tought either it connect to half the triangle's side. I have drawm some demo maps and it gives good results. But 20 triangles is a lot, I tought maybe having pannels of 4 or 2 trangles and then tile them as you want to recreate the world map.
In order to eliminate the half hex problem, I think there is a way to place hexs in an isocahedral shape without using half hex. The only problem is that it makes cutting much harder to do.
Using other shapes could also be interesting and more simple. An easier shape could be the 8 triangle (8 sided die) map.
Other kind of projections can be found on this web site. Very interesting.
