"Draw Something" is the #55 paid app on the app store STILL. So clearly it's bringing in and has brought in a ton of revenue since the ac (acquisition was in March). Sure not $180MM but it was also an acqui-hire. I think this could have ended up being a great deal for them, despite the negativity. It's not all about one game.
#55 paid app is not at all impressive given how much they paid for it. For that price Draw Something would have had to stick around the top ten, probably the top five, for quite awhile to make it worthwhile.
