I'm going through this a bit myself right now. Just sounds a little like burnout. You can get burned out even on something you love. Maybe taking a break and investing in another hobby for a bit would be a good idea. I have no doubt you'll find your love for gaming again. But right now trying to force yourself to enjoy it isn't going to make your relationship with it better--might even have the opposite effect. Take some time and come back for a game that looks interesting or exciting when you feel like you're ready to dive back in.
