I have site which is about little fighter 2. I only use adsense and I make 1$/day with 8000 views. This is English site. 50% traffic is from Poland (2 months ago adsense pay very little money for traffic from poland. It's maybe 3 times less than half year ago) You can see alexa stats here: http://www.alexa.com/data/details/traffic_details/littlefighter.biz URL: http://www.littlefighter.biz This site is about only one freeware game but have a lot of views each day. Can I try CPX or tribalfusion or they don't take this kind of websites?
With 8000 views per day, using PPP (Pay Per Play) you could make up to $160.00 or more per day. They estimate $0.02 average per ad played.

You can also hear a sample of the 5-second ads your visitors would hear on the information page below. This could be well worth your time... Good luck!
