This won't happen.It's simple. People would rather pay more upfront than monitize on the backside. People arent excited to pay more but a higher price on the front end means that more games will come out with less bs on the back end. The cost to makes games have gone up and the market is saturated. Ignoring cost increasing is naive, the money has to come from somewhere.
Idk how some of you don't know this, but these publishers aren't hurting for money. They simply want to keep making more money. The mtx market won't slow down with $70 games. In fact, it'll continue to get worse.
games may be more expensive to make. But EA, Activision, Ubisoft, 2K, etc. are making waaaaay more money than they were in 2005.
