It took almost the entire year, but Card Crusade achieved more than $10,000 in total revenue this year! Total sales on iOS reached $6,770, whereas Android reached only $3,800.
After the app store's cut and expenses to create the game, we've grossed roughly $6,000. Considering the game took 2 people roughly 250 hours each to make (including all hours spent on development, design, marketing, community building, legal, and other), that puts us at an hourly wage of $6,000 / 500 = $12 per hour.
Not bad for a part time gig!
