This was the first game that I've ever used a "game card" to pay for my subscription; I would have joined a week and a half earlier, but I didn't like the credit card agreement (too many hoops to jump through to cancel, and no chance to play out remaining credit after cancellation). I don't shop at Target that much, mostly because of the extremely poor access to parking at the unit closest to my house.
The front cover art is interesting, so for people who haven't had a chance to see the cards--here's the front:
As a note, I am at the minimum for RAM and video (in fact, it's 32MB worth of integrated video on my notebook); and, while I do have lag etc., it isn't any worse for me than for anyone else (and much better than some people I've heard about that do have fancy video cards). I'm ready to rotate in a new desktop, and I'll likely go with at least 1GB worth of RAM, but I'd have no reason to add on any fancy video cards, as I won't purchase it just to play games. I actually use the RAM for large satellite/aerial images, and other GIS/mapping applications.
