Personally ive almost never enjoyed gaming alone. I can count the singleplayer games ive finished on one hand. I almost exclusively enjoy playing games with friends. CO-OP, PVE, PVP, you name it. As long as i can play with friends and we can progress together im happy. Long term progression is my favorite, really seeing something grow that youve all done together is great. I enjoy MMO RPGs but also games like Minecraft, Factorio or Satisfactory.
As others have already mentioned breaking the pattern is the cure to boredom. Maybe try something new? Look for a genre youve nerver played or bringa some friends onto a Minecraft server. Maybe join a community and find some people to play with if no friends are interested. Or just take a break. Sometimes we ned to leave the cycle for a bit to be able to enjoy it.
You can check ProtonDB for specificerar games compatability. Most games from steam just install and run as usual. But other launchers and some games with anti-cheat can be a bit more wonky to get running or just dont work at all.
