One other point, the net cafe explanation definitely makes sense for games like Warcraft III. When I was in Taiwan when the game came out (this was many years ago), I played it at a net cafe. The game doesn't require a unique CD-key for each Battle.net account, so players can just start up a free account and play online in the net cafe. In this case, Battle.net accounts would not reflect sales numbers at all.
