sherringon456: Oh so you have bad internet, I can see why you don't now.
tinyE: XD No I'm on a satellite with a VERY limited bandwidth and a shit connection. Maybe I'm wrong here, and if I am please I want to learn, if I have to be on line to play and I lose my connection, even if just for a minute, doesn't that mean when I get it back I have to restart my game?
If your connection cut while playing a steamworks game, it will just queue whatever it need the connection for, like sending achievement or syncing saves, to the next time you're back online.
Although: if a game update has start downloading, you won't be able to play that game until it's finished. If you use the save on cloud thing, your autosave/quicksave/checkpoint progression may get lost in syncing.
And if your connection cut before you launch the steam program itself, you won't be able to play until it's back. Unless you ask it before to go in offline mode, but then you won't get updates, and won't be able to buy/install new games. And when you eventually put steam back in online mode, you better hope your connection is in a good mood, because it won't let you back in offline before every game update has been downloaded.
