I can turn that around too. Why would Epic, EA, Ubisoft produce flop after flop even though they have access to your innovative game design holy grail? As i said, you need to stop being so deterministic in your views.
But that's just it...they are.
How many game genres are there? 30? 50? 100?
Now take a look at the top 10 - 20 most successful multiplayer games today. They all fall into 4 or 5 genres.
1. Battle Royale
Those 5 genres adhere to the principles presented in the OP far better than the other 30 - 50 genres.
You also have to consider this. Games now take 4 - 6 years to develop. That means if a new era of multiplayer arrives in say 2017/2018...the majority of studios are in active development on their old era multiplayer games. They have to push the old **** out, which takes time.
Knockout City (old era) had a 6 year dev cycle. That means it got started in 2015, before the new era arrived. Is it any wonder that it flopped? Overwatch dominated at the end of the old era. Overwatch 2 is an objectively better game on every level and it can't stay afloat. Not surprising.
That's why I tell everyone to watch the games that started development AFTER the design revolution showed up. Games that began development in 2018/2019 will be built using the lessons of the new era, not the old era.
Unfortunately, games take 4 - 6 years to make so the wave won't fully hit until 2022 - 2024.
