Cav, Seri and me invented a whole new kind of world that TP is.
There would be some kind of TP Dollar. (TPD)
There will be 3 levels of Fly.
1st - learn to fly on a machine
2nd - learn to control a flying machiine with your mind
3rd - YOU CAN FLY WITHOUT ANY MACHINE!
People learn how to fly a machine that only last for 5 mins for every fill.
And people will have to fill that flying machine with Coke or Pepsi.
Coke being the most basic fuel, and Pepsi, being somewhat higher grade than Coke (and thus will be more expensive).
And there would be no more animals. Instead, aliens will replace the animals (birds, cats etc) in TP and there will be a course to teach you how to tame them. They are ferocious and will bite your head off.
And you pay TPD to a system to make yourself happy (or to create sadness for others). Once the system receives your money, a laser beam will shoot down from the sky towards you or the others you have targeted.
There will also be fighter jets parked below the fountain and Bedok Reservoir (just like the X-Men) so as to defend (or attack) other threats (from other polys lool).
And TP will also float off the ground.
There will also be 2 major shopping malls located above TP (5 mins and 1 sec of flying) so only those who learn the 2nd and 3rd level of Fly are eligble to enter the shopping malls.

And the most major way of earning TPD?
Auction guys!
And to get more money, the people will have to get more guys to be auctioned in TP. That's hwo you earn TPD :D
(ok, that was just to irritate Cav)

There were much more crap but this is what i can remember for now :D
