After last year, in order to "control" my spending on Steam sales I made a vow to only buy games that are at least 75% off...
So far, I bought:
AntiChamber
Fallout:New Vegas Ultimate Edition
GTA4
Saints Row 3
Spec Ops: The Line
Thomas was Alone
The only problem I have is that I forgot that Saints Row 3: Full Package was also on sale and by the time I realized it, I had already bought the main game already.
Curses! 
On a different/kinda-off topic question:
For those who have Tomb Raider on the PC, is the menu and upgrade menu in-game clear and easy to look at?
What I mean by this is that, when I rented the xbox version from gamefly, the game's in-game menu on my monitor (I play console games with my computer monitor) was very blurry and very hard to make out (especially when I'm trying to upgrade something--I couldn't even make out the words because they were soo tiny and blurry, so I just guessed 99% of the time).
The rest of the game, however, was cyrstal clear.
I tried messing with the settings and stuff but no luck. I can play other current and past games without this problem with my computer monitor+Xbox, so it could be the xbox version of this game...I hope?
I tried looking up a solution for this problem, but it seems like I'm the only one.
I've been wanting to this game from Steam for a while, but I'm worried that'll happen again, so, I've been holding it off...
