Do steam achievements work in offline mode? I want to play something but literally everything I want to play right now has achievements.
I've gotten achievements in Saints Row 3 and Skyrim while in offline mode. The notification pops up when you get them. Then when you are in online mode again playing the game it pops up again shortly after you start playing.
I was surprised by both games, but I got multiple achievements in each while offline.
Edit: Obviously this was all in the last month, which is probably why there are conflicting reports. I imagine this is something they've fixed recently.
