The
Yarnspinners and
Yarnspinners 2 games for Dominions 2 were essentially collborative fanfic. Large parts of some of the stories had little to do with the actual game, so they weren't strictly AARs. The stories are still all there in the threads, if you want to read 90+ pages of it.
YS2 was lots of fun, but lots of work. And I miss Sedna and Puffyn.
