Which country has the most plays?

Hello,

I have always been interested in languages and I am learning a few of them.

Because my favourite books are plays, I was wondering which language has the richest literature in that regard (not only in quantity but also in quality).

I'm not counting English and French because these are my main languages. I speak some Spanish too, I don't know if the Spanish plays are good or not.

Do you have any insight?
