Call of Juarez looks like it could be fun, but it's still 10 bucks. I'm conditioned to pay less than 6.xx for a full game, and much less for something like hotline miami.* The Humble bundle has out shined steam sales for almost going on a year for me.
*hm is awesome. the presentation is, uh, aggrerssive, yet the core of the game is some pretty solid fun for a couple of hours. maybe more. http://youtu.be/qqS51B4sdGc
(if you like games, tb is a pretty honest dude when you're out there sifting out the decent stuff through the piles of shit, I'd rec his videos/reviews/whatever.)
