Two major things:
gaming the interface is as involved or more than the actual gameplay, and is often required to "beat" AI which cheats.

RTS games are pure shit for me because of nonsense like this, because the genre usually combines tedious actions with cheating AI.
Playing an FPS with a controller is similarly stupid, especially because the action has to be slowed or simplified, enemies stand around with their dicks in their hands, and everything feels retarded and immersion-breaking.
Second, cramming players with completely different agendas into the same game, and not in a fun MMO class-based way where players have to work together in different ways for the same goal, but a completely fractured community full of cheaters, trolls, metafaggots, social/dramafags and other subcultures. It completely destroys the atmosphere and immersion of a game. Mirror-zombie "players" in VRChat, chinese gold farmers/bots, wallhacker/aimbotters in FPS, MOBA metafags who ragequit out over "wrong" picks/builds etc.
It would be much better to be able to pull cosmetic-artfags together with meta minmaxers, gamerbros and others through clever gameplay and rewards, but to really do that you have to under-develop the game rather than overdevelop it towards desired player outcomes. Most games now are directed for the pursuit of corporate profit by similar
(((people))) who also run the casino industry, so that's why everything is bland and soulless.
The social aspects of games for party and community-building have been neglected. Imagine trying to gather 4 other decent human beings in a DOTA 2 allchat or any other lobby. Impossible. Developers and most gamers just point to tranny groomer discord "servers" for community building but that has many obvious downsides. The other side is that even decent communities stagnate and fragment, as anyone can see with any number of dying multiplayer games these days. Having a fun multiplayer game with a decent community really is a full stack problem, made worse by the death of communities IRL and replacement with brown hordes. Most likely games won't be good again until a country decides to be unapologetically pro-White and produces a decent game studio.
