- Actor Existence Limbo: Yuka Imai's retirement and the subsequent auditioning for a replacement is a major factor in why Rutee is one of the last remaining veteran characters to receive 5* gear and a new Mirrage Arte.
- All-Star Cast: The video games voice cast boasts talents such as Natsuki Hanae, Kosuke Toriumi, Kana Hanazawa, Ryohei Kimura, Tsubasa Yonaga, Takahiro Sakurai, Katsuyuki Konishi, Rina Sato, Yumi Touma, Kanae Ito, Rie Kugimiya, Ami Koshimizu, Hiro Shimono, Toshiyuki Morikawa, Miyuki Sawashiro, Ai Kayano, Yukana, Takashi Kondo, Nana Mizuki, Ryota Ohsaka, Nobuyuki Hiyama, Kenichi Suzumura, Hikaru Midorikawa, Saori Hayami, Tomokazu Seki, Toru Okawa, Takeshi Kusao, Kentaro Ito, Eri Kitamura, Kenji Nojima, Akira Ishida, Takehito Koyasu, Ryoka Yuzuki, Jun Fukuyama, Soichiro Hoshi, and Yuko Minaguchi.
- Cancellation: The English version due to poor revenue among other problems.
- Cash Cow Franchise: Meanwhile the Japanese version prints money.
- Content Leak: Datamines frequently reveal future content long before they're supposed to be announced, especially collaborations with other mobile games.
- Creator's Favorite: While the team behind Rays wants to make sure everyone gets represented, it does seem like they're favoring a few games:
- Given that the main scenario writer was also behind two previous Tales games (Symphonia and Abyss), it shouldn't be surprising that the first batch of returning Tales antagonists hail from those games and that the story features some Cloning Blues.
- Tales of Eternia is the biggest one; while it does has a small playable cast, they were the first cast to have all four "core" characters (Reid, Farah, Meredy and Keele) added to the game. And it only took mere couple months from launch (with all four of them added in relatively quick succession), as opposed to someone like poor Sophie, who was in at launch but then ended up sitting all alone for more than half a year.
- Tales of the Abyss also gets obvious love—Luke is recruitable (in his post-Character Development form, no less) out of the gate, and the very first side event in the Japanese version was an Abyss event that also introduced Tear and Jade. It's a little less obvious in the global version, since that event was pushed back a little (as the launch event in Japan was considered a bit incomplete and didn't actually have Mirrage Arts for the two; as you'd imagine, this led to criticism, leading to a rerun soon after where the Artes were available, which is the version that was run in Worldwide). And then, of course, who ended up becoming available during the Summer event? Guy, naturally.
- Even before Guy's addition, who else had a sprite and nexus shard hidden away in the game's files? Anise. And one of the reasons she wasn't added sooner seems to be the developers having trouble animating her and Tokunaga in battle.
- With the addition of Natalia and Asch for the month of June, Abyss becomes the first game to have the entirety of its playable cast playable in Rays.
- In addition to the entire playable cast available, Sync The Tempest also becomes playable in the main story, and Dist is being teased as well!
- Tales of Destiny also got a ton of love early on. While other games might get side events, Destiny's characters end up with effectively three whole story chapters devoted to them in quick succession, and unlike a few other games, all three main characters—Stahn, Rutee, and Leon—were the first ones added to the game.
- Anima synergy-wise, Orange have the most characters so far (three from Innocence, seven from Zestiria, and six from Berseria), while Blue has the most games represented (Xillia 1 and 2, Radiant Mythology trilogy, and Legendia).
- Follow the Leader:
- Rays takes some fairly obvious cues from Final Fantasy Record Keeper when it comes to the design of its gacha and character-acquisition systems: namely, characters largely come from events and the main plot, and the in-app purchases and gacha mechanics are all about getting more equipment and Mirrages, generally. Very few people really complain about this, though, since it's part of why FFRK has been as successful as it has for as long as it has; it means, so long as they keep up with the game, F2P players never have to worry about missing a favorite character. Rays even tackles one of the criticisms about FFRK: Rays actually gives the characters a chance to be themselves and interact with the Rays-original cast, unlike the largely mute stat blocks of FFRK.
- Invisible Advertising: A common complaint about Namco's handling of the English version.
- No Dub for You: Considering the sheer size of the cast and how most voiced dialogue is restricted to battles, this was to be expected.
- No Export for You: With the global shutdown of Rays taking place at the end of Arc 1, Mirrage Prison will remain in Japan.
- By extension, every event after Ludger and Julius's event will remain in Japan as well, including the two events that take place before the beginning of Mirrage Prison.
- Out of Order: The event, Mieu's Big Adventure, was released later than intended in English, presumably due to the original Japanese version being incomplete in terms of characters' equipment.
- Post-Script Season:
- Screwed by the Network: Just being a mobile title and an entry to a niche series in the Western market already put the game at a disadvantage. The lack of advertising and questionable translation didn't help much either. And thanks to the Japanese version, players also knew what would be released 4-6 months ahead of time so they knew what to save for. Ironically, the one change from the Japanese version that actually improved the game's quality of life (abandoning the lower tier gacha currency) ended up giving players LESS incentive to spend money on microtransactions.
- Schedule Slip: Very rare but it happens.
- Talking to Himself: In a similar case to J Stars Victory VS, Tomokazu Sugita voices both Gintoki and Alvin, and Gintoki lampshades the voice actor joke.
- What Could Have Been: Marcus was implied to join the party or at least become playable earlier in the game with datamines supporting the theory but nothing ever came of it. He is also the only original enemy character (not counting the Final Boss) to have a cut-in during his Limit Break.
