My most favorite video game economy was Habbo Hotel, actually. Because few people actually bought coins, people were caught in a deflated economy almost constantly. And since special events or buying furniture from the store was the only source of supply for the demand, a whole economy formulated around furniture for coins, etc. I just thought the dynamic was neat. Additionally, Spiral Knights also had an interesting model -- access to levels was gated by something called "Energy," and you were given a cap and a given regeneration rate for energy up to that cat. "Crystal Energy" could be bought for real money and exchanged for in-game money, so it was an interesting deal -- the game created an automatic sink for money in energy.
