I hope Google In-Game Advertising will be available for all traffic and not limited to 80% US or UK only. Why don't they just increase the required game play per day?
Current Requirements: 1. Game plays: Minimum 500,000 per day 2. Game types: Web-based Flash only 3. Integration: Must be technically capable of SDK integration 4. Traffic source: Must be 80% US & UK Traffic 5. Content: Family safe and targeted at users age 13 and up 6. Distribution: Must be able to report embed destination and have control over where games are distributed https://services.google.com/events/adsense_games
So you need to hire one guy to do this: 6. Distribution: Must be able to report embed destination and have control over where games are distributed Insane rules, but then again do those big arcade sites earn so much, is it worth it? Per click is small ammount for that niche.
I haven't seen a site with In-Game Advertising yet. It's more easy to have your ads being click on games.
