I was browsing the releases of Blackjack - http://www.giantbomb.com/blackjack/3030-107/releases/
And it says the release is 1994. If you hit edit you will notice it's indeed a fuzzy date with only 1994 entered as information.
However, if you call the same release with the API - http://www.giantbomb.com/api/release/3050-96606/?api_key=(your key)
So will you get no expected_release_* data but you will get a release_date
I find this strange and misguided. How should I know that this is a fuzzy date?
