games today used to be made by gamers that got together with an idea they all used to agree would make a good video game and were working from inspiration and a grass roots community and made small companies. Then wall street figured out that the video game industry was making more money than movies, and all of a sudden all these capitalist economists showed up and started making games based on target demographic numbers and this means they are now trying to mass produce art (which by nature is impossible). Then what do you do when your company is in trouble or having a rough time competing? just buy out the competitor!
and then phones came along and half the video game companies jumped ship and tried to go over there where they proceeded to make some of the crappiest products in history and rely on microtransactions etc which straight up is a conflict of interest to gaming itself and are catering to a new generation that wouldnt know their heads from their rumps if their lives depended on it (sry kids, but your generation is an abomination).
Overall there just isnt the demand for better games. Why would you bother when you can spend a quarter of the time and energy on something crap just as many people will buy because they dont know any better, and throw away in a week but have a few shiny movie sequences?
Its all about dollars and sense...
