A Facebook application game featuring an agricultural utopia with no seasonal changes (either spontaneous or seasonal), a market with an unchanging supply and demand and no competition, restless and immortal workforce and livestock, and an overabundance of happiness.
Damn. I need to save up for a mansion in FarmVille. No problem, I'll just grow bananas and potatoes right next to each, collect an endless supply of produce from my happy, unabused animals, sell all my goods to a market that will obviously buy them at the same price every time, and then build my mansion within 5 seconds. Yay!
