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.
