Welcome to the
Steam Deal Thread V6! You can find link to past threads at the bottom of this post. Read post #2 of this thread for Steam FAQs and more.
With the V6 Thread, we're trying a slight formatting change. We used to list every possible Steam deal in the OP, but they change too frequently for anyone to keep up with (even in the Wiki format). So now, we'll leave regular minor sales out of the OP. This post will keep track of major sales (Winter sale, etc.), Steam deals available through other sellers (like Amazon), Preorder deals, and Group Buys.
I would still greatly appreciate help from you folks at home in keeping this smaller-scale OP up-to-date. This is a Wiki post so anyone can contribute. Wiki instructions:
Thanks for your help! If you notice a sale has ended, feel free to delete its line from the sale list. Of course, if you see something does need to be added, then kindly add it to the list.
Make sure your changes match the thread's format! For example, every game that's on sale is part of an unordered list. When adding a game to the list, copy an existing line and update the link, title, and prices. That way, the format stays correct. Do not list percentages off! We list the original price and the sale price here. If you have any suggestions for major changes to the post/thread, PM me (EastX) about them.
Steam Sales - Updated 1/22
CAG Threads Featuring Steam Games on Sale Elsewhere - Updated 1/9
Preorder Deals - Updated 1/10
Group Buy Deals - Updated 1/9/13
Several multiplayer Steam games are available in 2-packs or 4-packs. These packs offer a discount over buying multiple copies of a game separately. We also maintain group buy trade threads for several games, so please use those threads if you're interested in setting up a group buy.
Free Stuff - List needs updating with F2P games!
There are several free games and mods on Steam. These are a few choice ones; you can find a full list here. Note that free games are not permanently attached to your Steam account like actual purchases would be. You'll need to manually download a game again from the website if you uninstall it.
Steam around CAG
If you are interested in joining the
Steam CAG Community or participating in a trade or group buy with fellow Cheap Ass Gamers, please do so in the dedicated threads and not in the deal discussion thread. In the dedicated threads you will find CAGers with the same specialized interest who will be much quicker (and happier) to respond than in the Deals thread.
Past Special Sales

Steam Retail Key List
What is a CD key and where can I find it?
Steam's explanation and list of Steam-activatable keys
The CD Key is a serial number with a combination of 13, 18, or 25 letters and numbers - it can be found on a sticker inside your game's case or printed on the game's quick reference card. The CD Key acts as your proof of purchase for the game - Steam Support may ask for it if you need to establish your ownership of an account. It is recommended that you keep your CD Key in a safe place to ensure the security of your account.
Other Keys that can be redeemed on Steam (CAG tested & verified)

- The Ball (bought @D2D, tested by voken)
- Supreme Commander Forged Alliance (gives both FA and original, bought @amazon, tested by vism)
