Invest your Jacksons elsewhere.
I actually really, really liked this game. I would say it's the most fun I've had with a sim game on Newgrounds. The concept and execution is great. HOWEVER: this is still just an online flash game. Twenty dollars for the full version? Is that supposed to be some kind of joke?
Let me put it into perspective: Several weeks ago, I got Age of Empires, The Rise of Rome, Age of Kings, and The Conquerors all together for TEN DOLLARS. One month of World of Warcraft costs less than FIFTEEN DOLLARS.
Please, show yourself a little respect - don't spend twenty bucks on the "premium version" of some online doodad.
