I was early beta-tester so Ive played this game for a year or so longer than most. And I like to play RPGish. So Ive shifted to really REALLY large maps quite awhile ago. In fact, for quite awhile all of my games have either been a quick test game on the mini-map battle simulator which only has 6 provinces, or its been 1000-1500 provinces. Like these..

If you want, two are available here..
I recommend MegaMap and TriMega. Altho if you dont mind the lack of graphics then Max_oo1 has the advantage of being a wrapped map (the edges connect so no edges and corners).
