Battlefield 3 on PC doesn't exactly work right now—try later
The single-player portion of Battlefield 3 was a major disappointment, but most of us bought the PC version for the multiplayer. That's going to be a harder beast to review, so we're slowing down to take our time and explore the maps, vehicles, and character classes. But we're running into a problem: the PC version of the game doesn't really work at the moment.
The console version is having its own difficulties, with the 360 servers going down temporarily last night, but the problems with the PC version seem to run through the entirety of the multiplayer portion of the game.
DICE titles have a reputation for being absolute train wrecks at launch. The chances of this launch going well were about zero, so many PC gamers seem to be sucking it up and making the best of it. (Source
