I have a feeling that those of us who do make it over that initial hump probably end up playing long enough to make up for it. It was not exactly easy for me to get into initially, and if I hadn't had a group of people to play with, I may not have made it to five hours...or even bought the full game, for that matter. After I pushed through that and got sucked in, though, it's gone on to become my second most-played game on Steam, at least since it started tracking time played.
