This is a really interesting game, I got to watch Chris producing and growing it over time and then I got to watch him talk about it at FGS the other day. It's been great watching his revenue climb and the game grow, when it first started it was tiny.
If you're making multiplayer Flash stuff you really should talk to him - http://playerio.com/
This was a much more interesting video than I thought it would be. I'd never thought the payment models he uses in the game would have brought the revenues they have for him. $50 for a smiley face just seems ridiculous and yet people were happy to pay for it.
