Storygames:
Besides the obvious?
I suppose Briar_rose, I played several of her games, loved them all.
Madglee's mommy is an extremely well written game, and he seems to be an extremely good writer himself (makes sense, he used to be a teacher)
Sindriv's Homo perfectus seems good I only ever played the first four before I lost interest (Not a big superhero fan), but others seem to greatly enjoy his work
JMGskillz's star wars fanfiction was amusing to play, I mean, he basically butchered the series (I'm not a star wars fan, haven't ever seen any of the movies, the most i;ve done is read a single book that was placed right in the middle of the series, so, completely out of context. I also played a few star wars games, that have nothing to do with the original plot. But even I know that he just shat all over the codes of both the Sith and the Jedi. It's a fanfiction though, so it can be forgiven.) however I still enjoyed the storygames, and his writing has greatly improved since the first one.
Thatguy, the one who made the wallmart game, he's a pretty good puzzlemaker, and the wal-mart game was a great one.
Skysworne's stories aren't too bad either.
Urnamo's Sotrygames are good.
Donteatpoop's ducky park was hilarious, I think you'd enjoy it.
There are A LOT of people who make games on this site, and A LOT of games, would take too long to list them all.
Poetry:
Rommulus all the way, that poem he wrote for the sonnet contest easily trumped the other two that were shown (Not that i'm saying yours wasn't good- it was, but his was just that much better. Seriously, it was fantastic)
You're good as well, and BZ's entry into amy's poetry contest wasn't half bad either. As for the rest, I can't tell, we haven't exactly seen a trememndous volume of poetry flow through the site.
