Steam - All id Games 50% Off, Clear Sky Delayed

I noticed on ggmania that this weekend's special deal on Steam offers up a great deal for id Software fans. Every id Software title on Steam is now 50% off! Word is: "This weekend only on Steam, id Software games are 50% off. This includes the id Super Pack for only $34.99 (over $200 worth of games). Or take 50% off individual titles such as Doom, Quake, Wolfenstein, Commander Keen, Heretic, and Hexen. Offer ends Monday, September 8."

In other Steam related news, S.T.A.L.K.E.R.: Clear Sky is now officially delayed. This news comes just hours before the game was officially set to be released on the digital distribution platform, and days after news that retail stores would also suffer a delay. The new countdown places the release on the 15th of this month. If it's any consolation, gamers can now pre-purchase the game from Steam for $35.99. This price is a limited time offer, with the regular price being $39.99.
