If I go into multiplayer in the US server I see a different list of games than when I got to the UK server in Steam. I was going to try out a game with my bud in the UK, but some jerk hit is car while he was in the store and left, so I have to wait a bit. Before we were not seeing each others games. Once we were able to Thursday after validating local files, but even that didn't work Friday. Hopefully this will help those with friends in other regions hook up for their games. Just go into Steam > Settings > Downloads and all of you choose the same region.
