When you look at the pictures you can see much materials:
glass stones, wood pieces, tokens and tiles and for each player two player boards.
It seems that one of the player boards has a big "sun" in that sun you build a map with hexagons.
The hexagons could have a different landscape (it remembers me a bit of Settlers of Catan).
You need a table which is big enough for all the materials...
