A decicated server paid for until 2008, $500+ USD (got cheaper as my friend is the owner)
A custom forum template from phpbbstop.com $100 USD
A small and catchy domain registed via namecheap $8.85 USD
The server/source/client for the game $200 USD +
Paid advertising at WauShare.com $10 USD

All for $15$? Uh.... what? You mean $1500 right?
