While the folks at the Humble Bundle continue to ignore my suggestion for a role-playing game-themed Humble Bundle, this week's Humble Bundle Weekly Sale is as close as you can get: for the next six days consumers can get 15 games from indie RPG developer Spiderweb Software's catalog DRM-free and with plenty of extras.
The Spiderweb Software bundle includes The Geneforge Saga (contains Geneforge 1, Geneforge 2, Geneforge 3, Geneforge 4: Rebellion, and Geneforge 5: Overthrow), Avadon: The Black Fortress, The First Avernum Trilogy (contains Avernum, Avernum 2, Avernum 3, and Blades of Avernum), Avernum: The Great Trials Trilogy (contains Avernum 4, Avernum 5, and Avernum 6), and bonus game art and hint books.
If you pay more than the average price (currently right around $3.40), you'll get Avernum: Escape from the Pit and Nethergate: Resurrection. A majority of the games are available on Windows, Mac and Linux too. If you like old-school CRPGs, then this is the bundle for you.
You can find the system requirements for all of these games here.
You can check out the Humble Bundle Weekly Sale at http://www.humblebundle.com/weekly. Check out the video to your left for more information on all these games. For the record, Spiderweb Software's Jeff Vogel is a living legend (as he claims in the video), having survived this industry for twenty years as a small independent developer... Respect.
