So... let's say I'm a portal owner, and there's a new game out "SuperMalioSisters", and its a super good game, getting real hot... It's not mine, I didnt sponsor it, I have no links in it, but if I win the "auction" so to speak, plays of that game will come through my site?

And then I pay for the traffic and hope to recoup my expense?

Question to portal owners out there: Do you pay for any of your traffic currently? (The closest example would be Google Ads and paid text links)
