I was surprised they released a demo at all for a multiplayer game.
Although to comment on the game as a whole, If the original was just an experiment (As I vaguely recall valve stating themselves), and was still a roaring success, and L4D2 will likely be the version of the game that they fully commit to, after proving that the formula works well, then it will definitely be one of the games to watch this quarter. Although, that being said, it's still very much a gamer's game, the sort of thing you hear after doing a bit of research or watching the news. But, seek and you shall be rewarded.
