I'm not really happy with what i will say, and even if use twitch as a compare tool is really non-sense. He is right about the actual way the game take and what the younger generation want. Sadly you can see that everywhere around you, in tv series, cinema and video game. The time of deep story who make you think and use your brain is dead. I see that every day around me, people want fast, easy game, with a lot of action and not so hard. More you need to use your brain less it will please the people. As i said you can apply that for almost everything around you now.
Look the last start wars take the old story, take out all the non-action part, put a lot of fight and explosions and sell it. At the end most of people say is one of the best star wars.
I wished more than everything Fallout series avoid this kind of "evolution" but be realistic is made by a company who only do that for money. So make easy action game sell more that what they will do.
