Good Old Games - All Interplay Games 50% Off

Good Old Games has a summer staycation sale where you can get 50% of all Interplay Games like Fallout

Here's a snip from the announcement:

Staycations’ are all the rage as the economy continues slowly staggering back towards recovery. But even if you're not looking to save cash on your summer vacation, there are still reasons why you should keep indoors, on your PC, and enjoy some classics. Vacations can be expensive (and dangerous!) so why put yourself through all the hassle when you can have a similar experience for much less with GOG.com?

The first staycation sale will end on July 4th 2011
