There are two things that worked for me when I was in your situation:

• Playing with friends, of course it applies only to multilayer games and scheduling free time for two or more people could be difficult but it works so well for this problem. We have a WhatsApp group to coordinate some gaming nights and play rocket league, age of empires 2, cs go, overwatch and others, recently we are replaying DS3 next will be elden ring when the dlc drops.

• Review games. I know it sounds absurd but I put some effort into creating an excel sheet with all the games I played and I reviewed them on what I think are the most significant aspects (characters design, level design, story, gameplay loop, graphics, sound, optimization just to name a few) I reached several reviews of the sheet and now it's very complete and complex. I like to complete games, fill the form and add them to the list, I usually complete at least the main quest, anyway Icontinue to play the game until I'm satisfied and I've elaborate a score for each category. This helped me reasoning on the game development, what it wants to tell me, the evolution of the gaming industry, I've figured out what I like and what not, all of this combined with the the genuine excitement about starting a new game to add to the list it's what re-enabled my passion when I was stucked like you are.

I hope this can help you. Send me a private message if you want to add me on steam and play sometimes or if you want a copy of the spreadsheet!
