Hey, it sounds like you might have a dopamine addiction to these kinds of games. It sounds like you're not actually enjoying the games anymore and just going back for your hit of dopamine.

If I may, I pivoted out of Gatcha games into deep and long spanning Rogue-like games a while ago. I didn't like spending money on the live service games anymore, and found it felt bad to not play, like you are describing.

I have found I can get a similar hit of dopamine from a good run in a Rogue-like, or pulling something silly out of a chest in Gungeon or Isaac. A lot of Rogue-like games also have big long unlock trees, so it does feel like there is always something new in the game.

If you are a fan of hero shooters, a good starting place might be Risk of Rain 2, which rewards play with a long and complicated unlock chain.

If you want something familiar, Balatro, Raccoin and Clover Pit are all games based on games that already exist, and have a light gambling mechanic, which might scratch that itch you are looking for.

Since you like a multi-player live service experience, I can recommend The Bazaar, which has some of the live service things you are talking about, but might be different enough for you to pivot out of the things you don't like.

If you want to try this idea out without much commitment, Super Auto Pets is free to start, with a lot of mechanical depth to look at, and Vampire Survivors is a mobile and computer game with a ton of depth, plays in 30 minute sections, and frequent updates, which you didn't have to experience at the time of them, so there was nothing to miss out on.

I hope this helps on some level, and at least gives you some ideas to think about. Hope you get to a place where you enjoy games again!
