Dragoonblade below should get off his high horse!
I'm tired of people getting all uptight and high and mighty whenever a game costs money. Dragoonblade probably wouldn't know it, but making these games actually costs a lot of money to make. At Hero Interactive, we have payroll, insurance, office rent, health insurance, energy bills and so on... When you have staff working on a game for several months, the bills add up.
The bulk of these games are still free which is AWESOME and the way I think we all want it to be. But even without the extra pay for features, the free stuff is A FULL GAME- far more content than most other flash games out there. Judge a game for what is included, not just what you can't afford.
You know what also costs money? EVERYTHING. Since ancient times we've been exchanging goods for money, it's not worth getting all worked up about now. If you don't want to buy it, that's Ok! That's how business works.
Bloons is awesome, gets my 10.
