Spiderweb Software, makers of the RPG series Avernum and Geneforge, are celebrating their 15th anniversary with a sale. Game bundles are 25% off, and everything else is 10% off. Some of the games are cheaper at other sites (such as Avernum IV, which is available at BigFish), but this is the first time I've seen Spiderweb discount the games at their site. There's a blurb about the sale at the website, but it doesn't mention how long the sale will last.
