Trivia / 13 Sentinels: Aegis Rim

• Acting for Two: All over the place, as almost every actor in the cast plays at least two separate roles throughout the game's story. This is never a coincidence; if two seemingly-unrelated characters share a voice actor - no matter how unlikely it may seem - those character will turn out to be different versions of the same person.
  • Iori Fuyusaka, Ms. Morimura, and Chihiro Miura are all played by the same actor, as clones of the original Professor Chihiro Morimura.
  • Shu Amiguchi shares a voice actor with Tetsuya Ida, who is his alternate self from the previous loop.
  • Tomi Kisaragi and Miyuki Inaba share a voice actor, since Miyuki is an AI copy of the Tomi from the previous loop.
  • Keitaro Miura is played by the same actor as BJ, who is also an AI copy of a previous loop's Keitaro.
  • Kyuta Shiba shares a voice actor with Fluffy the cat, because they're both fake personas assumed by Prisoner 426 - the Juro Izumi of two loops prior.
• Creator's Oddball: While Vanillaware has made a Real-Time Strategy game before, this game takes place in a modern setting rather than a fantasy one, and features downbeat, realistic character and robot designs rather than the stylized and over-the-top designs of previous titles.
• No Port For You: One of the Japanese eighth generation era videogame to, inexplicably, not have a PC release despite since around 2014, a lot of Japanese games are released to the PC due to architecture similarity between PS4 and PC making porting easier. A Nintendo Switch port being made that is not only competent on weaker technology but ran better makes the decision not to port more confusing.
• Pre-Order Bonus: A PlayStation 4 version of Princess Crown is given via a download code for those who preordered the Japanese version. And just like the previous rerelease on the PlayStation Portable, it has no plans to be released outside of Japan.
• Release Date Change: Was originally slated for a 2018 release on PlayStation 4 and Play Station Vita, but was delayed to 2019 with the Vita version cancelled due to longer time needed for development.
• Shrug of God: When asked about Ryoko and Renya's Maybe Ever After status in the epilogue, George Kamitani said that their status is whatever the player wants it to be.
• Sleeper Hit: In Japan, the game sold slowly at first, but continued to build momentum until eventually its sales exceeded Atlus' expectations. Including digital sales, the game eventually sold over a million copies.
• Troubled Production: Specifically the English dub of the game. Due to the Covid-19 pandemic, the recording process ran into multiple hurdles. The team started out with studio recordings, but soon had to switch to remote recording over video conference calls, with actors, directors and engineers forced to do their work online. Many actors had to set up recording studios in their homes, with some even having to record in their closets to achieve appropriate quality. Given all the problems they faced during production, it`s a miracle the dub turned out as good as it did.
• What Could Have Been: The game was originally going to be released for the Play Station Vita alongside the PlayStation 4, but the Vita version ended up being canceled. Understandable, given the number of enemies in the Destruction section. Even the base PS4 stutters at times (especially when using Missile Rain). Luckily, the Nintendo Switch version ended up filling the void of a portable version of the game years later (at the cost of the lower resolution, while handling three explosions on the same area smoother). There were also large changes to the scenario during development: For example, at one point, each of the thirteen protagonists had twelve possible story paths, making for a total of 165 possible variations.
