The game is currently set up as a pyramid scheme of sorts.

The game is totally broken.

Think about this game a month or two out with nothing changed. The people who got in early will now have a bunch of high level buildings that they built for free using the initial seed money. New users who enter won't get any ROI. This game will die in a month or two if it isn't drastically changed.

Hmmm... are you sure this isn't an allegory for something?
