For me it was Terraria, Satisfactory, Tetris Effect Master Mode, Minecraft with Mekanism mod & CSGO / CS2 (almost 2000 hours in CS alone).
Edit: There are so many answers that I might only reply if I have something interesting to say. I will read all of your answers though. 🙂
RuneScape: I can’t believe I played the game after the removal of free trade. It was such a poorly run game, and I’m can’t believe anyone still plays it anymore. It’s unbelievable how arrogant mod MacDonalds was, and that I only quit in 2011 after I got scammed trying to sell the account.
League of Legends: this is another case of really great game, but incredibly poorly managed. Having Phreak be the balance lead just feels like shit, and made me feel like shit because I kept playing thinking it’d get better. This is a very global, very competitive game that was balanced around competitive play and optimizing spectator happiness. You can guess just how fun it was to play a character that was deemed “unfun to watch in worlds” and get absolutely gutted by Phreak’s team. The opposite was also hilariously true… they buffed certain characters so they’d sell more skins or because spectators like watching them. I finally quit after having to swap my main several times because they nerfed or reworked it and left me playing something else several times.
i played before the pandemic, then became a member year round until last year(albeit sustained from ingame currency instead of irl money). ive seen multiple freakouts ingame, why they are quititng 1 was just blabbing about wasting his life on rs then logged off.
