hello

I'm searching for some stats related to mmo browser games.
Do you know any places (if they exist) where I can find some info about:
- amount of playing users vs registered users (mostly active accounts for certain amount of time, as the amount of all accounts are mostly being shown on game's website)
- game's websites visits/openings (unique users, returning users etc) beside such website info collectors as alexa
- approximate incomes and costs (although costs I can estimate by my own)
Well, nobody wants to share its income, but maybe you have some news how much developers of certain games earned by selling their product, income from advertising or any other things related to incomes ?

It would be great to have the info split between different markets (eu, us, global etc)

There are couple mmo games on facebook. Those qualify too.

I know only mmodata.net service, but they do not gather info about browser mmos, despite dofus and runescape.

any useful info would be very appreciated
