History VideoGame / XenobladeChronicles3FutureRedeemed

** One of the Heart-to-Hearts in ''1'' has Riki extol the pleasures of hot springs to Shulk in Valak Mountain.

When traversing the Black Mountains, Shulk, who is now in his forties or fifties, will sometimes mention that he would like to visit a hot spring.

* DramaticIrony: At the end of Chapter 4, [[spoiler:the party and Na'el are taken to a recreation of Klaus' world which Na'el views as a paradise where with enough resources to go around for everyone]]. These statements are deeply ironic to anyone who's completed ''VideoGame/XenobladeChroniclesX'', as one of the game's central conflicts stems from the fact that [[spoiler:Earth did ''not'' have enough resources to go around for everyone and that the corrupt Coalition government (which also exists in Klaus's world) favored the already-privileged during Project Exodus's evacuation of Earth, leaving commonfolk like Lao's family to die. There's also the radio broadcast playing in the back ground while she gushes about how perfect this world was describing how Dimitri Yureiv's attempts to pass a human rights bill through the Federation government failed, resulting in the war that destroyed the earth and is implied to be at least part of his StartOfDarkness and all the horrible things he does in Xenosaga.]].

** Since Rex and Shulk are party mainstays and direct immigrants from the old worlds, they have a lot of anecdotes to share about the various familiar landmarks you'll encounter during the story. Shulk gets the most, as the DLC contains more ''1''-themed areas (especially with the main town being his hometown) but Rex also gets his share, such as the ruins of the Lumos Pillar.
*** Rex at one Affinity site reminisces about the time the Urayan Titan ate him, Pyra, Tora, and Poppi during ''2''.

** A conversation with Rex about the Ancient Ruins has him discuss their age using BuffySpeak (calling them "ultra-mega-ancient"), harkening back to similar lines of his ''2'' such as when he describes Morag and Brighid similarly.

** A couple of sidequests in Colony 9 call back to Colony 9 sidequests from Xenoblade 1, such as one where the party needs to find a lost wedding ring, and another where they help the proprietor of the local curry shop gather ingredients (herself the granddaughter of the curry shop proprietor from the first game).
