I completely disagree with you here. Yes there are games which have micro transactions, many of which did not have them in the past, but that doesn't mean that awesome immersice games that only charge users once are dead. They're even more available now. The Witcher is a usually touted as the prime example, although it's a few years old at this point. PS4 has a few exceptional titles like God of War, Horizon, Days Gone, Uncharted, Spiderman, Ni no Kuno, Shadow of the Colossus RDR 2, in the last year. The switch has games like Captain Toad, Mario Odyssey, breath of the Wild, Mario Kart, Case of Distrust, super smash Bros while PC had Frostpunk, Hitman 2, Battletech, Into the Breach.
All excellent games in their own right, all released in the last 12 months, as standalone experiences. If you want to you can jump into any number of paid for multiplayer (division 2, world of Warcraft, destiny, COD, PUBG) or f2p (Fortnite - disclaimer I work on it, Warframe, League of Legends, path of exile, PlanetSide, Apex Legends). Yes some of those games have micro transactions, but for the most part they don't actually interfere with the game. Yes you can cherry-pick some of my specific examples and tell me in wrong, but you can't even begin to claim that gaming is in a bad state right now.
