I don’t usually buy DLC (that’s downloadable content, for those unaware). A lot of it strikes me as silly, like new character skins or some in-game items available for a few dollars. Not things I’m interested in. Then there’s DLC that adds quests or new areas into an existing game, which seems destined to be awkward — an obviously tacked-on affair that doesn’t gel well with the main game. More reasonable are the DLC offerings that are essentially the expansion packs of old: new levels, or separate game areas designed to be tackled after the main game is over. Still, I would need to really like a game to go for one of these, given how many other games I have to play.
But in the case of Deus Ex: Human Revolution, I did really like it, enough to grab it’s DLC add-on, The Missing Link.
