I didn't come to this decision in a vacuum, either - I come to it as someone who does not want to pay the price as established. I'm extremely penurious. almost outright parsimonious when it comes to money. I don't like spending it. So when I heard how much the expansion was going to cost (the day the pre-orders became available) I immediately balked at it. It's only ten bucks more to buy Titanfall, I said to myself, and that's a completely new game. And then I read this post by Kim Acuff (who often comments here at WoW Insider as Ember Dione) a developer on Skylanders, and I started to rethink my position on the relative cost of the expansion, how much it should cost, and the validity of the whole "as expensive as a new game" discussion.
Because here's the fact - each WoW expansion has effectively been a new game.
