My pick-ups so far: ICY
($3.25 - 75% off) is a post-apocalyptic RPG taking place in a new Ice Age wasteland. Rated Mostly-Very Positive The Vanishing of Ethan Carter
($3.99 - 80% off) is a first person mood-driven mystery. Rated Very Positive BloodGate
(89¢ - 90% off) bills itself as an "Action Puzzle RPG"; basically an RPG wth Match-3 combat elements. Rated Positive Blood & Bacon
(89¢ - 10% off) is just ridiculous gun **** involving shooting and lots and lots of lots of pigs. Looks like it should be horrible but is rated Overwhelmingly Positive. Only 10% off but still under a buck and I'll wind up playing it with friends. Melody's Escape
($4.99 - 50% off) isn't on a super deep discount but I've been playing it since I bought it on the first day of the sale. It's a "Play to your music" rhythm game, set as a side scrolling runner. Levels are generated by the beat/tempo/energy of your tracks and ranges from "really good" to "pretty good" depending on how nontraditional the structure is. Even the weakest levels ("Energy peaks") are pretty fun if not as whiz-bang cool as when it finds a strong 4/4 beat. Rated Very Positive.
Don't know if I'll get anything else. Certainly a far cry from the days where I'd drop three digits during a seasonal sale.
