Well if you're looking for stories most in need of a review, we just had a big contest which led to a lot of entries hitting the site at once, and with so many not all of them have gotten a lot of feedback yet.
There's a list with links in
this thread, although they're mostly right there on top of the new storygames page too.
They cover a variety of genres since all the entrants picked from a list of prompts, so I'm sure you can find something you'll like.
