I really want Dishonored and the full version of Civ 5. But I've already bought Bioshock Infinite, the Mass Effect games, and the Saints Row games. Coupled with my current backlog (stuff like Tropico, FTL, the classic Fallout games, and a whole bunch of other stuff, not to mention my ongoing adventures in Skyrim), and I think I have enough to last me until the next sale. And who knows, maybe Dishonored and Civ 5 will be even cheaper then.
But I still really want them.
