With QuakeCon being the big event this weekend, you won't have failed to notice the daily deals on Steam that are running throughout the weekend. Today we've got RAGE reduced to half price, Saturday will see all Fallout games (+DLC) reduced by 66% and all id titles are reduced by 75%.
GOG.com has cut the price in half of all their Tremendous TopWare Titles promotion so you can now nab the likes of Two Worlds, Jagged Alliance 2: Wildfire, and Enclave for between $2.99 and $4.99. Meanwhile, GamersGate is having a 2K Summer Promotion, reducing the likes of Mafia II, BioShock 2 and Duke Nukem Forever by up to 75%
Amazon.com has knocked 20% off London 2012 in case you're feeling the Olympic spirit and there's $20 of in-game goods for the free-to-play Stronghold Kingdoms if you link your game account to Amazon. As always, if you find a weekend-specific PC game deal, post it in the comments below.
