http://store.steampowered.com//sale/quakecon_2014 That Quakecon 2014 bundle looks *really* good if you don't already have anything in it: Wolfenstein: The New Order, Elder Scrolls Online, Dishonored GOTY, Skyrim Legendary, Fallout 1, Fallout 2, Fallout Tactics, Doom 3 BFG, Doom II, Master Levels for Doom II, Final Doom, and Ultimate Doom, all for $99.99.
The separate Dishonored GOTY special is the same price that it was in its flash sale during the Summer Sale. Still, it's never been a lower price before.
Amazon is also running some Quakecon specials:
Of note, the recently released
Wolfenstein: The New Order for 50% off, $29.99 and
Return To Castle Wolfenstein at 75% off, $2.49. Both games are also on sale in the Steam sale, but they are significantly cheaper on Amazon.
Edit: it appears that these Amazon deals are the same prices as the previously mentioned Green Man sale, which I'm guessing let's you use an extra discount code on top of the current price, making the Green Man deal better...
