Definitely going to pick up that Assassin's creed: pirates ahoy game.

That new god-game from Populous also.

Castle Story, not sure it's on Steam though.

Brutal Legend, never got around to playing it.

The X-com expansion if it goes down to a 10'er.

Remember Me, looks interesting.

It's on steam. Although, the development has been rather slow.

Not sure I'll have any money for these sales, but

The Witcher

Assassins Creed

Not sure about much else, I've got a lot of games that I haven't really played that I've collected thus far. Probably should finish them before I start up with new ones.

I'm at the point where these sales rarely do much for me.  Everything old I want, I have.  Everything new I already paid for, won't be on a big enough sale this time to get me to buy, or already has been on sale and I bought.

Me old school Ghost Recon 1, Rise of Nations, Street Fighter 4, Xcom UFO Defense, Payday 2 dlc, Mirrors Edge, Dark Souls 2, Rainbow Six 3, (would like to get Watch Dogs but I doubt the sale will go 50%+) and Goat Simulator. 

The sale hasn't started yet.

No, just hoping.

My wishlist:

The Secret World

Wolfenstein

Tropico 5

Shadowrun: Dragonfall

Planet Stronghold

Van Helsing II

Castle Story

Wolf Among Us

Farcry 3

I Am Alive

a bunch of DLCs mainly for CIV5

Lets see how many i can get for €50

Also got Startipia for $1.49 cant go wrong with that price.

Didn't get anything on the first day.  Not too much I wanted, or already had.

What is the benefit of steam wallet besides an extra minute taken out of purchasing games/dlc/etc.?

It might be a tool for him to help plan the budget for his game purchases. There is also the possibility that he purchased any of the myriad "Steam gift cards" for a better than dollar per dollar ratio.

You get steam dollars when you sell steam cards, so there's that. (e.g. you may have 2-3$ in your wallet which isn't enough for a whole purchase but why not use it?)
