I'm extremely picky, but I'm lucky because I have a game I love to bits that's been consistent the last two decades. I don't think it's a bad thing, and I've come to accept it. I still play games socially with my friends, even if I wouldn't have played that game by myself.

I went through the same thing you did, trying games that are popular and finding that I don't enjoy them that much, and then thinking that I've become jaded and no longer enjoy games. However when I do play a game I enjoy I enjoy it very much indeed, so perhaps I'm not jaded after all.

There's no accounting for taste.
