I said it was full of content, because DampCat was suggesting that because it has less content than other games it was devoid.
I am using full in a contextual sense, in that it's not as if the game has open expanses of nothingness that are just boring traverses with little to nothing to do.
But for the type of game it is, with its game play and game mechanics, it's certainly full of content.
To compare it to a similarish game, Killing Floor. Where the game doesn't change in terms of what you do or the levels you pay if you're playing multiplayer. Killing Floor has a lot more levels and weapons than Left for Dead 2, but I would say it isn't as full of content as Left for Dead 2.
