Yeah, I agree with solo. ESPECIALLY if we start giving credit/points for forum storygames, everyone will do those instead of actually writing anything. Look at how many we have going right now already.
Forum storygames are *much* easier than writing a real quality storygame. After all, the author doesn't have to come up with an idea until someone actually picks it, and they only have to write one "screen" worth of story at a time.
Forum storygames can be fun, but they're no substitute for real storygaming.
Although I do think Rommel might be onto something with the "giving forum storygames their own space" idea-- or at least identifying them through their titles in the forums.
