Arches fucked me up more than anything else from Echo Project did. Most likely from the story's relevance to me. Honestly? If someone asked me, I would be tempted to say don't play it. It's the best thing Echo Project has written but it's fucked. I had warnings for the other games echo project has but the other games did not hit me as hard as this.
Overall 10/10 story with an almost unbearably realistic ending, considering everything that happened throughout the story and everything is written, the experience the characters felt were real, but everything else? That's for you to decide and the writers certainly did their job to make it seem either way.
(Also i say this is "the best thing produced by echo project" but its easier to perfect something short rather than their longer projects! The team does great.)
I didn't cry, but i will randomly think of this story and the bittersweet arch shaped place it has in my mind.
