You only get to download the game for up to 6 months after you buy it. This is completely lame as it means that you have to back it up somewhere just in case you lose it. For an additional $6 you get to download it for an entire 2 years. <sarcasm>>How brilliant is that!</sarcasm>>. Compared to a service like Steam where you can download it an arbitrary number of times to any pc that is connected to the steam service. Anywhere in the world. At any time. Until they go broke (but that will be telegraphed well in advance I hope).
Six months. Silly billies!
If it wasn't for carbon-14, I wouldn't date at all
