Most games are mediocre, I'd say that about 30-40% of the games that I try are good in my opinion and then there are hundreds that you simply don't even want to try.
Then again; many games are objectively good even though I don't like them. But I still feel like the majority of games are mediocre, just as with music, movies and books, most broader entertainment is mediocre, but it's still entertainment.
