Recently finished Limbo in a couple of nights. It was neat, but lost the impact by the end. In part because I played it without sound—the GNU/Linux port was just the Windows version bundled with Wine, and it required some messing with PulseAudio, which I was too lazy to do. I guess it'd get old really fast anyway, when repeating a puzzle a dozen times. I don't feel like I missed much apart from a bit of atmosphere; I used to listen to the OST in bed, while falling asleep.
I've also tried DEFCON (it was too easy against bots and I couldn't be bothered to look into multiplayer) and Uplink (should be nice, but I can't find the time and motivation to get into it). Next on the list is Bastion.
