There's this side quest in the theme park portion of Living Memory that's about a little boy that's looking for his brother. I recommend doing it if you haven't, but I'm going to explain how it ends below.
Living Memory returned him to being a child because that's when he was happiest, playing with his little brother, but once he he comes to the realization that he can't find his brother because his brother didn't get on the last train out of Shaaloani before Heritage Found appeared, and he immediately becomes an elderly man, wistfully recalling working on the railroad with his brother and much of the rest of his life, and in the gap of his memories left by the machine, he chooses to find joy in knowing that his brother barely knows that he is gone yet and has his whole life in front of him. It's so tragic I'm getting choked up recalling it now, and thinking about my own brothers.
Yeah. I cried a lot in Living Memory, so very clearly the zone and all its implications impacted me, but it was NOT from the MSQ characters or the dialogue or any of that. It was just the setting, visual storytelling, musical direction, and having a bit of my own personal experiences to draw upon and empathize with. And the nagging sense of a huge, HUGE opportunity wasted... Hopefully they'll do better going forwards.
