Welcome. The site is a lot of fun, if you don't behave like an idiot. Most people are Intresting enough to chat with, and the discussions in the Lounge are likely to intrest you. (though we, I especially, aren't good at keeping the discussion about the original topic)
and about the story games. If the game is shit, it will probably be called shit. If you put work into the game, you will probably get a rating above a 4, though if you don't put effort, (and actual writing skill) into your story, you aren't going to enjoy your comments.
Anyways, enjoy your stay here! If you have any questions, ask someone else. Preferably one of the moderators. :)
