Few weeks later...
New TK Demo-version record numbers in both Population and Money, as far as is commonly known.
After intense agrarian revolution, Hoptopia ended to usual tilt after three long days of work soon after the situation drawn as above. 30+ hours.
Remove card is the most important card of the game, thus those vast expanses of fields, of which about half are bulldozed over already existing housing-districts.
Hoptopia's prosperity money-wise is just a side effect of active efforts to maximize farming of Remove and Tavern cards.
Not sure how much tighter a map can be arranged with 5000+ populations. Not sure is it really worth of time needed for searching that out either...
Maps of Hoptopia 2114 (44x37), 3512 (47x50), and 5304 (56x58) in same scale. There are more screenshots taken, but I draw only these three maps to demonstrate how the kingdom grew. The Castle's relative place stays same in all above maps as the West and North boundaries were already "locked" in pop. 2114 map and further expansions were made only to East and South.
Hopefully at least somebody find these posts interesting enough to not to get annoyed their apparent bloggish nature. I've put hundreds of hours to this game (DEMO!) and to making maps from my game projects, wanting to share them to others. :)
