For me it's slightly complicated but it's Genshin Impact. I started playing it on release but anyone else who did will remember it was pretty barren and I got bored super quick, and with not having any characters I really enjoyed playing I ended up dropping it within 3 days.
I love BotW's gameplay loop of mindlessly meandering about doing shitty puzzles for small bobbles, but with all of the good exploration utilities locked behind gacha I really didn't enjoy it.
Then in 2023 a friend who had a bunch of re-roll accounts gave me one with Ganyu and Mona and I tried it again, got a bit deeper, had a good time, but still didn't enjoy it. Picked up 2 more 5* characters (Childe, Nahida) but that early in the game they weren't needle movers for my still quite barren teams.
It wasn't until I tried it again last summer when Navia was on banner, and rolled her, and instantly fell in love with playing as her that the game finally hooked me and I started sinking dozens then hundreds of hours into it.
So I regret not sticking with it for all that I missed out on all the daily shit and now feeling rushed in a game with a fomo model, but I also regret coming back to it because now I've sunk more than a few hundred dollars into the game and am on the fucking hamster wheel.
