But he is right in the first 1/3rd. FPSes are ruining gaming. Though he missed the point it only started being retarded when they started being made for the lowest common denominator. Remember when FPSes didn't have the whole soldier bullshit and you were literally moving at speeds of cars and actually required reflexes? When you could carry more than 3 guns and the option of 50 others, which were in fact the same thing as the original 3? What happened to a lightning gun that can shoot ninja stars, guns which shoot 6 rockets at a time, perosnal flak cannons, personal cannons that shoot cnanonballs bigger than you?
Though, his arugment about 3rd person over 1st person just sounds like the argument of a scrub who can't play well enough.
Gaming matured, that's what happened. Over the top action had to go and make space for realism. That's why you are moving slow now. That's why you can only carry a couple of weapons at any given time. That's why your health regenerates automatically.
...wait. That doesn't make sense.
Microsoft is to blame. Ever since they've entered the home console arena, they have worked hard to change the perception of the market by manipulating game journalists. Today the Xbox brand is the golden standard in gaming (at least in the USA) and most websites will tell you in their editorials and articles that all consoles should strive to be like the 360. First person shooters didn't mature, but Halo was put on a pedestal to become the standard for the genre. That's the point where things started to go downhill.
In the last few years we've repeatedly had news claiming that the money is on consoles and that the PC isn't worth it anymore. This lines up perfectly with what Microsoft wants, full control over gaming. They realized that they don't have a chance to get the major Japanese talent on their console, so they focused on the other big thing: The American talent. However, that was predominantly working on the PC, so they did everything they could to build the perception that consoles are the way to go, along with the obvious moneyhats of course.
Feel free to write this off as a silly conspiracy theory.
