NoobsTown v5 has been out for almost two months now, and already various towns are starting to reach the final Size capacity (448). I believe Fatnoob said that this will be the final map for as long as we can help it, so for an indefinite amount of time. Many Mayors are ambitious about where they see their towns in the many months, and hopefully years to come, will be. Since the consensus of players has already established they would rather have a small amount of towns that are well populated and large, rather than everybody and their dog owning a town that has a population of maybe ten (this is why the town pricing is relatively high) I believe that we may find it necessary to increase size capacities. Here are a few reasons why (any that I miss will hopefully brought up in the comments)

a. Most of the Main towns that have transcended the various incarnations of Noobstown (Like Forthwind, Kochirakoso, Mapleforge, Empire and The Black Forest) and many v5 unique towns have reached or are nigh at the pinnacle of expansion. They are full of various communities of builders, farmers, miners, et cetera. The problem comes at the fact we are only 2 months into this incarnation, and we are already at this point. Therefore, many may see it isn't a
far-fetched claim to say a few towns might desire a little more space

b. We are growing, and i mean really growing. In less than a month we doubled our previous registered members on the site, and a good bit of those numbers are correlating into regulars on the server. So, as the rate of new people becomes higher and the rate of town expansion slows to a stop, It's going to get crowded. (think of all the space that goes into cosmetic areas of the town and attractions, then think of whats left for actual residency)

c. If we stay the way we are, as many towns reach cap new towns will HAVE to be built to keep up. This means we will run into the same Piles of Piles of towns we had in previous versions.

d. The size cap is impeding on towns expansion, safety, and overall creativity. People have told me about how they have unclaimed paths in towns so they can have more space for residency or Necessary improvement. This means that these paths or other unclaimed areas will be open to griefing and modification by outsiders. People are literally giving up structural integrity for the sake of some extra land

e. Towns are well spaced out, capacity could increase to 1000's of chunks extra and you would most likely never bump into another towns border (unless they purposefully built it next to you, in which case agreements could be struck out) Meaning that on the grand live map every great down is dwarfed by the blocks and blocks of space stretching out in all directions. Space that cannot be harnessed for creativity.

I could list the endless benefits that an expansion could bring to noobstown, but i'd prefer others to reply and integrate their thoughts. My best hope is that this at least reaches attention and will be open to future consideration.

You also never see any good arena, embassy, shop or public plots because it contributes to the creators total owned plots. Ruining valuable opportunities for well maintained shops that allow only the owners to use the utilities while remaining public.
