You don't have to edit the map, but the size and Over Poweredness of you and mikos expansion is crazy. You started with half of the Arabian Peninsula and you somehow got all of Africa without a fight. I'm out.
I started with much less than half of Arabia. However I did expand daily and increased the size of my new claims over time to keep them of relatively similar proportions as far as land mass, which nobody had any objections to while I was doing it. I'm sure nobody will bar you from doing so as well. Also, I have been fighting, but I really don't see the point in saying that AC troops take over more land every time it happens, instead I just update the map.
Miko hasn't expanded except into Europe just recently, in like thirty or forty years, plus he had his old nation, the BFFSR (or whatever), to use as a foundation.
If you like you can claim more land for your starting area so long as you don't overlap with anyone else, you may possibly include Japan and North Korea for example. As host, I won't stop you.
