Yeah, I keep hearing about the error 34... Usually, for all games, it's a good idea to wait at least a month. That way, most bugs are known to the developers and patches are on the way (if not there already). Except for EA. They don't concern themselves with patches. They just release another game.
Speaking of single player online, since I finished DA II, I am between games. So I decided I was going to finally finish my Civilization 5 game (I conquered every opponent except the strongest, so it will be an interesting fight). So I open Steam (because the games plays through Steam). A message box appears, telling me I have to update the game to a more efficient format. I don't really have a choice as if I press cancel, the game game doesn't launch. So the update starts, and near the end, there's an error message, saying it failed to update the game. So now the game won't work. After a quick internet search, I saw many many people also have that problem... No solutions were put forth... :/
