Playing with map size areas...10x10 and 20x20 have a huge difference as many people know; in fact, 20x20 is VERY unpopular and usually results in bad gameplay just because of the speed at which armies can tech and emplore "super weapons." There is practically no t1 or t2 phase there....
In order to alleviate some of the dullness and redundancy of 10x10, I'm going to make some 20x20 maps that have playable areas of 13x13, 12x14, etc, etc. For 5x5, I'd like to try a 10x10 with 6x6, 6x8, etc, etc.
My first map concept that I want to eventually reach after gaining some experience with the tools is called "Der Schöpfer"
It will feature navy and land gameplay where there will be important, strategic land points and access to the ocean on the north west and north east sides of the map.
PLEASE NOTE: This concept drawing is not finished and I plan to upload another five iterations adding more and more detail. It's a hand-sketch - hopefully that's obvious - so please excuse the appearance of a lack of symmetry.
