It's a closed system. It's not just an ESO thing -- they have rules and regulations that govern all games, if you're going to do something it has to work a certain way. It doesn't matter the way that we want to do it -- it has to fit their requirements.
I'll give you an easy example; payments. When we do stuff on PC, we manage it ourselves, it goes through our store, we manage the whole thing. When it goes through somebody else, that someone is doing all of that; taking your money, charging your PayPal, and then transferring that information to us.
This is just inherently a different process than the one that we have, where it's our store and we just have to make sure our system works. It's the same thing on PSN -- you have to just make sure that all of that stuff communicates. When you start adding up the pile of things and everything that we learned from launch, it was clear that we needed to take the time to do this right, because it has massive ramifications if it doesn't work right for the consumer experience.
