SpaceChem has been surprisingly fun, albeit confusing. Spiral Knights is good too but I'm not sure how much more I will genuinely play it. Trine is good as always, in the short 1-2 level doses I inevitably end up playing it in. Atom Zombie Smasher has been absolutely amazing though. I've already beaten the default campaign twice since I finally started playing.
I've been unable to play any of the Sam & Max pack due to busy Steam servers though. -_-
