I was wondering if anyone had any opinions about how well these monetization services work?
And if there are any other options for webplayer games that are not based inside FaceBook?
And if there is a service like this that also covers iPhone and droid as well?
For iphone I recommend the storekit and in-app purchasing, simply because it's linked to the person's apple ID so they never lose a bought item and never have to sign up for a second service which will certainly lose some customers. If they've logged in before and saved their details they don't even have to login again to buy something.
Also Apple iAds has been implemented for ad revenue.
Not sure about Android.
For facebook consider dime rocker.com They have a social networking and monetisation plugin and free hosting. They will also help customise your game for free if you use their monetisation services (e-wallet, in-app store etc.)
