We  wouldn't and couldn't  call a video game "pretentious" before the 7th generation, but when games like MGs4 and CoD4  innocuously, but effectively, sacrificed an immense amount of their previous elements to attract new players and SELL MOAR, unfortunately, what shouldn't have to be done was done, and waves of pretentious games were on shelves, and players inevitably played them, until they forgot what a "good" game means. 
 
But we need extra adjectives for some games, pretentious hipster shit is what I call the games that use extra, but ineffectual effort to attract MOAR players .
 it's obvious that AI can't sense body movement with a million simultaneous motions, third party developers as always will not make good and decent games for a motion controller, and Three-dimensional is not going to work in games as it worked in movies. (and it did not worked good in movies neither)
 
These gadgets are embodiment of inability of developers in making original, new games, and I don't think that we will ever see a good game again.  retro gaming anyone?
