Income from free gaming site

window.document.getElementById(‘post-3845’).parentNode.className += ‘ adhesive_post’;What do you think is a probable income for a free gaming site using ppc advertising per 1000 daily visitors?
Let’s assume the worst case scenario, that the players only see the ads when they enter the site but not when they play the game.
I am confident I could create a popular play for free poker site with perhaps 5 000 daily visitors or even more, but I am not certain the incomes would be worth the costs ($10 000 for software + server costs).
Another possibility is to advertise poker rooms but I am not sure it is so profitable (have tried it in a smaller scale) since the players are freebies.
What is the best way to make money of such a site and is it worth the costs? Feel free to speculate it may be a difficult question to answer just like that.
