COOL!!! Definitely as you've noted... I seem to remember that TFP hard coded the 16k limit, unless you made a map with Nitrogen. Anyway if you look closer at the cities before and after - you'll also notice that total lootable area has dropped massively. I haven't looked at the numbers but I've guesstimated that it's above 25% to upwards of 40%

There is a definite noticeable drop in sky scrapers too. I miss the old time - city at 0-0 cause you didn't venture in there till you got some serious levels and stuff! And you did get serious stuff for going there too! lol Oh well. Thanks for adding the 12k option!
