I wouldn't necessarily agree.
There are genres of hardcore games which don't emphasize violence and weapons. Grand strategy and 4X games (like Crusader Kings and Civilization) typically stress the fact that violence is only one tool out of many, and usually not the best tool. Construction games, like Dwarf Fortress, Sim City, and Kerbal Space Program put less emphasis on destruction, and more on construction.

I think people call certain games "hipster bullshit" because they think those games are trying to be different only for the sake of being different, taking themselves too seriously, and/or are written pretentiously. Sometimes people are right, sometimes people are wrong. I've never heard anyone call Portal 'hipster bullshit'.

I think that Mass Effect was turned more and more into a shooter because shooters are what sell, nowadays. Its hardcore rpg components were toned down because the average casual gamer doesn't really care how many newtons of force their telepath character can exert with a "force push" ability, or want to sift configure dozens of equipment options, for 4 different characters.
