For it to be a reasonable argument to me personally one would need to explain why the devs nowadays deserve to be compensated less for the game than they did when it launched in 2018.
100% disagree, and frankly this take is baffling to me. Every game ever released is affected by inflation, but Wube are the only devs I've ever seen react to that by increasing the price of their existing product. Most devs just create and sell new content, which I don't think anyone has a problem with.
What is baffling you? I personally prefer fewer quality games supported for a long time rather than small sh*tty releases over and over. Also, games are getting cheaper and cheaper every year due to inflation, which is not a good thing. Again, as a consumer I perfer less more expensive games compared to a lot of cheap games, or more likely to microtransaction driven games, which are automatically corrected for inflaction.
This is why I believe that someone should make a first step and work towards this being the norm. When I pay rent, I get a letter every year that my rent was increased by X % due to inflation, and basically everything is getting more expensive, why would game devs should stay behind?
