Vampire Survivors seems to fit the bill: no story, a bit of tactics, you level up to get new items, and enjoy killing hordes of enemies at once. After every run you can unlock power-ups for the next run.. It's one of my most played games in the last few months. It's one of the classic "just one more run" type of games

Path of exile new league (season) drops in 9 days, perfect time to familiarise yourself with basics and hit the grind, and oh boy is there grind to be had.

Stardew Valley lol

It's very treadmill, but can be fun.

D2R. I know plenty have played the shit out of D2 already but somehow I hadn’t and after seeing how shit D4 was D2R has been great on the deck. Runs flawlessly.

Siralim Ultimate maybe? The Steam description: "Siralim Ultimate is a monster catching, dungeon crawling RPG with a ridiculous amount of depth. Summon over 1200 different creatures and travel through randomly generated dungeons to acquire resources, new creatures, and loot."

At some points, you need to rethink your setup and incorporate the new stuff you've found along the way to be able to mindlessly grind on but I've played for 160 hours so far and having a blast trying different strategies. Evoker is my favorite class so far - casting so many spells before the battle even begins that the enemy never gets their turn.

Try Dinkum, it's like a mixture between Animal's crossing and Srardew Valley and a very chill and relaxed game. There are a bunch of levels for pretty much every one of your skills and it takes a while to progress into the game.

Grim dawn

Monster Hunter World/Rise. After mastering monsters it becomes a grind for parts.

If you're into idle games at all, try out Melvor Idle. Costs $10 but you can try it for free on a browser if you want to see what you're getting. It's heavily inspired by RuneScape. Melvor is without a doubt the best idle game I've ever played, so if you're a fan of the genre and aren't afraid of the grind, I'd highly recommend it.
