While the game itself may be a bit short (all the campaigns (including the L4D1 campaigns) take about 6 hours to beat if you know what you're doing), the sheer amount of modding far outweighs it. There are absolute bucketloads of awesome new campaigns, weapon models, memes and all sorts of stuff to satisfy anyone's needs. The workshop is absolutely a highlight of this game.

Though a word of warning for new players: don't try any versus gamemodes if you're new. The community is rather toxic, but it never really affected me, considering I care little about it.
