Blocktopia is a gamemode where emphasis is put on making sure every single brick, every single item and vehicle, everything in general needs to be worked for, and unlike say a cityrp, you can
not get money for just sitting around and keeping the playercount up. Rather you must contribute something to the community. Likewise, a realistic market economy is simulated, where everyone can produce as much as they please and sell it for whatever price they see fit. And only if they manage to get players to buy their product or service, will they themselves receive money.
Property:

Lots will be 32x32 studs and in blocks of 4. (64x64 studs)
The center block will be for "government" use, that is, default spawn, bank, and park.
Lot types are currently planned to be agricultural, industrial, and commercial.
Shots showing Wink's barn with a few kinds of crops:


There are four types of crops at the moment.
Potato grows the fastest and costs the least, but also sells for the lease.
Corn is the next fastest and least expensive.
Then wheat.
Then tomatos.

Oil wells.
The ones with the red brick on top are capped/claimed.
Basically you need to buy a well cap for 30 mats.
Then you wait while the well slowly turns white (time depends on height)
When it's all white and the cap is glowing, click it to harvest.
You'll get a combonation of light and dark oil depending on the origional color of the well itself.
If you let the cap sit ready to harvest for too long (10 minutes) it'll turn blue and anyone can harvest it.
Light oil is used as a part of technology (also requires copper iron and mats), and dark oil is used for gas.
This is where mining and oil drilling will go.
I might make wood cutting it's own job, or an extension of farming, not sure yet.
Technology will probably be crafted from a combonation of materials, based on recipes.
Older picture of the GUI:

The GUI may or may not end up being required, but it will definitely help.
It will enable you to see stats in three categories, self, lot, and server, as well as complete actions like buying a lot or switching farming modes without having to use multiple slash commands.
