You know, Kongregate, the Flash game site which has achievements and stuff, making it sound like the Xbox Live of browser games, and developers can make actual money! You might think why would a games retail store would buy this company, but it makes total sense in that they want to establish a web presence.

A few Kongregate games have microtransactions; I wouldn't be surprised to see this become more common under their new overlords.

How can you resell used flash games?
