I love reading old, finished RPGs and making fun of how my writing was or how silly some of my characters were, then admiring the writing of others (*cough*Aman, Bethberry, mark12_20, Nuru, Imladris, Fordim, Durelin and others *cough*) and their well-developed posts.
My favorites include:
Search for the Lost Messenger, because it took several 180-degree turns near the end and is enjoyable to read.
Tapestry of Dreams, even if it's not quite finished yet because all the writers are just so great at what they do, and even if we don't exactly all have the same style it just works somehow.
Dark Seduction, because it was just so...so...it was just plain evil! *shivers*
And
Brotherhood of the Last Alliance, because even if the ending was quick and hurried, the character interaction was just so fun! Plus I got to play an especially evil character...
I also like going through to the end of games just to read the dramatic (sometimes not-so-dramatic) death scenes of my characters and of other people's characters. Sometimes it's rather funny to re-read those posts...unless you get attatched.
As far as threads that don't have to do with RPGs...I thoroughly enjoy reading both of the
'Are You Writing Serious Fantasy?' threads. They're very informative, and it's helpful to know that there are others out there with the same problems or issues that I have with writing.
Those are just some of my favorites, because I do enjoy loads of other threads.
