Well, I picked up one of the recent Humble Indie Bundles, and by God it was one of the best purchases I've ever made! Here's a rundown of my experiences.
Limbo: Adored the atmosphere and the puzzles were great. Was a bit disappointed that the scary factor went down a bit after the spider/evil kids section was over, essentially turning it into a dimly lit puzzle platformer with gruesome deaths, but I still loved it. Played through it three times.
Psychonauts: PC controls are pretty bad, and there's a nasty glitch on the last level that makes completing it a lesson in anger management, but on the whole one of the best games I've played in a long, long time. Wonderful writing, fantastic concept, beautiful execution. Played through twice.
Braid: I have to admit, I didn't really get into this one. Which is a shame, as with all the hype I was looking forward to it. The so-called story part seems to have been shoved in post-production, and I hate the whole "read it in chunks between levels instead of actually experiencing it" gimmick. The gameplay's solid, and the time twisting puzzles are clever and well done, but since story is a big thing to me the way it was handled just turned me off, especially since it could be removed entirely and you'll still have the same game. Didn't finish it, may return to it someday.
Bastion: ADORED this game! Had some control problems, but on the whole it was wonderfully creative and brilliantly executed. And the narration was fantastic. Played through three times.
Eversion: Yeah, I know it wasn't part of the package, but I picked it up about the same time. The platforming bits were decent enough, the puzzles challenging, and I liked the whole world change gimmick. Hate how beating it makes it go into time-attack mode though, as I wouldn't mind playing through it again normally. But overall, I enjoyed it.
I'm still working up the courage to give Amnesia a roll, and Super Meat Boy honestly doesn't interest me.
