It's primarily the Saturday NY Times crosswords that I do, as it's the only Times puzzle our local paper carries, but I do sometimes get the booklet of the newest puzzles from Amazon. I sometimes do the LA Times Sunday crossword, as our local paper carries that, too, but I don't like it as much as the Times' Saturday puzzle.
Oh yeah! I heard The Talos Principle was very good. I think I have it... I have a ridiculous game backlog so I wouldn't be surprised if it's in there.
Not exactly a jigsaw puzzle, but am playing The Talos Principle, which is a puzzle type game, like Portal (kinda sorta).
I have dozens on my Xbox that I've never even tried.
With me, I need to be able to invest a good 1-2 weeks for any game. Once I start one I have a tendency for it taking over my life until I complete it, ignoring almost everything else. After it's completed, I then go back and clean up the battlefield, trying to get all the accomplishments I missed, etc., which can take a couple of more days.
