I definitely think games are lacking in the length category. With the price of development, many games are trying to artificially lengthen their content with silly puzzles, or just going through the same levels but in a "Dark" or "Backwards" style. I think this aspect of a video game is actually quite creative in most instances (SOTN, A Link to the past), but its just something that has lost all of its novelty because its the "go-to" method of lengthening a game. I never really have the issues of beating a game too quickly because I'm the explorer type who likes to find everything his first time through. Thats not to say that even though I do cover almost every facet of the game, the games still seem rather short. so, to conclude: no, we're not beating games quickly, the games are just shorter than advertised (if you even listen to that filth anymore.)
