What do you have? And of course, what do you like?

Kotor I & II.

Civ IV complete or Civ V gold.

TWD is an experience.

Saints Row 2 & 3 are fun too

Machinarium is uber cheap.

I was considering the KoTORs, I have them on disc but I like the ease of Steam.
I already have CIv4 so I'd rather wait for a really good Civ5 Complete deal.
SR2 & 3 I have and are some of my favorite games. Machinarium I already have from a bundle I think, but it's not really my kind of thing.

Thanks for the tips!
I suppose I could've been a bit clearer with what I'm looking for, but A) it's like 6000 degrees over here and B) I was hoping for some interesting deals that weren't necessarily front page news.
For example Gnomoria or something like that, I'd never heard of that until I saw it mentioned on a forum somewhere (still didn't buy it though, if I don't forget I should check if that has a nice sale).
Or Sonic Racing Transformed perhaps?
I don't have a kart racing game on my Steam account I think.

I've played that Sonic thing when it was on a free weekend recently. It was fun is all I can say, because it was the first Kart game I've ever played and have nothing to compare it too. It's arcadey as fuck, but I imagine that's the point. You get to switch between cars, boats and planes in the middle of levels and the tracks are fairly interesting. Bonus points if you like Sega characters.

Gnomoria is a strongly dumbed down Dwarf Fortress. My friend has 125 hours on it, but he's also a person who has 110 hours on FTL, 133 hours on Prison Architect and 609 hours on Empire: Total War.

How about Street Fighter IV: Arcade Edition? That game is fun and has a nice competitive scene going. Also completely playable on keyboard, much better than on a controller in my opinion.

Total cash expenditure this sale: £0.00.

Games acquired entirely from selling those wonderful cards;

Retro City Rampage

Reus

Sword of the Stars: The Pit

System Shock 2

Gnomoria

Starseed Pilgrim

Triple Town

McPixel

Pinball FX2: Epic Quest Table

and a handful of backgrounds for my profile!

Good haul, eh? I wanted a couple of other things (particularly Jagged Alliance 2 Gold and Skyward Collapse) but I reckon I have enough to last me until the next sale :D

EDIT: also picked up 3 copies of Just Cause that I have no idea what to do with :-/

I got 2 twenty dollar gift cards to make all my purchases.

However I only got
Hotline Miami (which doesn't seem to work on my computer :( )
Faster than light
Heretic+Hexen collection (since fuck it doesn't seem to ever going to be as cheap as it was back in 2011; is it my imagination or did there used to be Heretic 2 in the collection as well?)
Binding of Isaac DLC

for myself.

the rest I spent on stuff to give away in the gift club or for trades.

I got almost everything I wanted already throughout the year so, surprisingly, Fallout: New Vegas Ultimate Edition was my only purchase this sale for $5. I was considering grabbing Skyrim, but I decided to take a miss. I already have enough stuff.

Edit: oh yeah, and I also got a copy of Just Cause 1 for $0.27. I really have no interest in playing it, but maybe I'll gift it to someone.

How many cards did you sell? How much did you play? I keep seeing people post about all the stuff they got from selling cards, but since selling prices are not that high for single cards, I assume you sold quite a lot of them...

I just left all my games running overnight for a few days to farm cards. At 10-25 cents a pop they actually add up pretty quick, paid for alot of games this sale.

The prices dropped heavily during the sale, loads of people got some decent piles of cash from them before the sale and at the very beginning of the sale.

Bah, can't decide if I wanna get Kerbal + Wanderlust and just redeem my Sonic Hits Collection

or

Get Wanderlust, Sonic Adventure DX, and Sonic Adventure 2 and just save Sonic Hits Collection for next Kerbal sale.

I'm not sure exactly, but I went over Steam's 150 sales limit and had to sign the tax form to sell more. I'd guess it was somewhere around 175 in total. And no, I didn't play much, but I idled a hell of a lot!

Whatever you do, don't use Process Explorer to suspend a game and save yourself the power consumption. That would be cheating, and cheating is wrong ;)

And....its gone :(
Bought:
Tomb raider (2013)
Borderlands 2
Universe Sandbox

Unfortunately, Heretic 2 has never been part of the collection. Hexen 2's expansion is also missing. :(
