Yes, if you set your PS4/PS3/VITA Turkish as language descriptions will be shown as Turkish. Although not all games support Turkish, there are some games that supports and 90% games that released in 1 year have this language. Like Uncharted series, The Last of Us, Fifa series, Battlefield 1 etc...
In a lot of games Turkish language is official. I'd really wanted the show you but I don't know how to upload a screenshot in this forum.
