I really enjoy the Alone hacks. Alone Among the Stars and Alone in the Ancient City are among my favorites and reprinted here, alongside a new hack with a spooky deep forest atmosphere that feels very different from a similar hack (Alone on the Rocky Beach, not present here). I think of Stars and City as medium weight in terms of time investment, and Forest as lighter.
I love having these games gathered together, though I wish Beach had been added.
