I bought it online. I cant imagine why id want to spend petrol money to drive to a store, queue up and pay money to some crappy retail establishment for something I could just download.
As a games developer, Im pretty certain the direct sales earn stardock SUBSTANTIALLY more than rteail per copy. I know that I earn around 8 times as much as I do from an online sale as I do from the retail copies.
The future of games purchasing has to be online, the only thing holding people back is broadband availability and some old fashioned view of owning the CD as being more secure. And You can burn your own CD/ DVD anyway.
To be honest, if I'd had to go to a store, I might still not own the game, but as a digital download, there was no reason not to get it.
