Civilization 4
Steam Fall Sale should begin soon (I believe possibly within 24 hours). So ready your wallets. 
Curse Steam Sales and HumbleBundle. My virtual Steam wall of games is overflowing with games I never play, but the prices are too good to pass up. "Maybe I'll play this game once in the future." So many lost hours of store productivity D:
Freaking blizzard... I'm so going to be broke by the time this month is over...

I may also go into gaming hibernation at some point. If I don't post for over 5 days straight send help :p
I can’t click on any of those… can’t risk getting re-addicted to WoW.

Steam summer sale day 1.
Terraria is a great game for 2.50 if you like the block building free roam genre.
Sleeping dogs at $5 is a fantastic deal. It’s similar to gta but more focused on hand to hand combat. Really fun game.
Left4dead2 at $5, fantastic zombie shoot em up.
Skyrim at 7.50 ( $20 if you want all the dlc as well) an absolute steal at this price. I’ve put well over 350 hours into it.
Trine 2 at $4 is a lot of fun with friends.
That's an insane deal on Skyrim. Absolutely a steal.
Battlefield 4 for PC.

Also:
Loadout for PC. Free on steam. I had a blast playing for an hour or so. It’s a game that doesn’t take itself seriously and is quite fun. It’s similar to team fortress 2, a bit more blood and violence though. There are micro transactions, but they aren’t pay to win, pretty much aesthetic things and aren’t actually needed to play it.
Definitely worth a try for free.
If you guys want a cheap quality and hugely replayable game over and over again, simply get open tycoon deluxe
That is some serious gaming at a seriously unbeatable price …$0 
Been a while since I updated here, honestly forgot about it. :X
Anyway, Steam is having their summer sale until the 30th! Each day there are a bunch of primary deals, and every 8 hours there are new deals in addition to the primary deals of the day.
Way too many great deals to list, but I use reddit as a primary source. http://www.reddit.com/r/GameDeals/hot/ They update very quickly, and often users provide their take on the various games.
The golden rule of steam sales:
Until the last day of the sale (check the countdowns on each game page), DON'T BUY A GAME UNLESS IT'S A DAILY DEAL, FLASH SALE, OR COMMUNITY CHOICE.
If a game is a daily deal, flash sale, or community choice THE PRICE WILL NOT GO LOWER.
That moment when Steam Summer Sale comes and you have no games left to buy, because you have them all.
