It's pathetic how you guys will openly admit to refuse purchasing an amazing game because it's not part of the download service you want.
To me (and I'm sure many others) convenience outweighs many other factors, including how good the perceived end product is. If I have to go out of my way to get a game that isn't that important to me, it's not going to be purchased.
For me gaming is something that I use to waste time, and the very little free time that I do have available isn't going to be wasted running around purchasing software through multiple venues.
At the end of the day I can only assume that your a bit younger than myself, and have yet to reach a point where gaming isn't the 'end-all-be-all' of entertainment.
