Emily v2 is a very sad story and Mark Piazza did a great job turning it into a show. Though it feels like storytelling, instead of a seancé. From the start to the end, we try to contact Emily, do some tests to see if we're on the right track and than suddenly, we reach to the end of the story, without the feeling of an actual contact.
Besides that, instead of explaining the effects thoroughly, Mr. Piazza decided to direct the reader to other sources (usually paid sources), which makes this piece a little bit hard to understand for beginners.
Still, a very good story and I recommend it.
