Here are some parts of Chained Echoes that you might have missed.
Chained Echoes is a tribute to old role-playing games. To do this, it takes parts of its story from several video games, movies, and other popular anime shows. Some of the references are pretty obvious, while others are made in a more subtle way.
Chained Echoes has a lot of hidden moments and secrets that add a lot of depth and flavor to the game. Some of these are references to other RPGs, but they are not the only ones. You’ll want to pay close attention as you play the game, whether it’s because of nods to Final Fantasy or Chrono Cross, hidden accessories, or just the way people talk.
Kylian’s Ultra Move References Final Fantasy 9’s Alexandria Castle

During battle, your characters can use strikes called “Ultra Moves” that do a lot of damage to one enemy or a group of enemies. If you’ve used Kylian’s move, you may have realized that it looks like a reference to Final Fantasy 9.
Kylian sticks his sword into the ground, which makes a huge blade come out of the ground and reach high into the sky. The blade that comes out looks like the sword in Final Fantasy 9 that is stuck in the middle of Alexandria Castle. If you don’t know how the design works, you might not notice it.
Princess Lenne Is A Chrono Trigger And Valkrie Profile Reference

The main character, Princess Lenne, is a pretty clear reference to Chrono Trigger’s Leene, but her last name hides yet another easter egg. You soon find out that Lenne is a princess who is hiding because she is rebellious, and you soon learn that her last name is Valkyria.
Tri-Ace made an RPG called Valkyrie Profile, which we think is what Lenne is referring to here. Lenne’s Ultra Move looks a lot like the Nibelung Valesti finishing strike, which we’ve seen in every Valkyrie Profile game. Add her last name to that, and you can see the connection.
The Alpha And Omega – Xenogears

Most likely, the first quest in your log is a nod to the beginning of Xenogears, a 1998 RPG. Your first quest in Chained Echoes is called “The Alpha, Not the Omega,” which you will immediately know as a quote.
Deeper than that, this quote is used in the opening scene of Xenogears, where the words “I Am Alpha and Omega, The Beginning and the End” crawl across the screen. It’s hard to miss, but when you play Chained Echoes and start noticing all the references to other games and cartoons, it all makes sense.
Woken Up By Mum – Chrono Trigger

Only people who have played Chrono Trigger will know what this is about. One of the main characters, Glenn, is woken up by his mother at the start of the game. This scene is very similar to the beginning of Chrono Trigger.
Glenn is just having a dream that he is going to war on an airship, but the opening is a nice nod to one of the best JRPGs of all time. It looks so much like a scene from Chrono Trigger that you might think Glenn’s mom is about to give you money for the Millennial Fair. So, they save that nod for a little while later.
The Devs Might Prefer Dogs

As you travel around the world, you will meet dogs and cats in Inns and in some towns and cities where they are just sitting outside.You can pet a dog if you go up to it. When you do this, a bunch of love hearts will show up above the dog’s head. If you do the same thing with a cat and talk to it, an angry sign will appear above the cat’s head.
Some cats will give you hearts when you pet them, but there aren’t many of them. On the other hand, every dog in the game will always give you hearts and never get mad about it. We all know that cats can be friendly and dogs can be mean, so there’s some bias here.
Some Dialogue Choices Matter

In some parts of the game, you can talk to NPCs and tell them to do something or not to do something. When Glenn is on the plane at the beginning of the game, you will meet two of these NPCs. One person is sitting next to some dynamite and saying he will use it to kill the enemy.
If you tell him it would be smart to use it, he will help you in the fights that follow. But if you tell him it’s not a good idea, he will decide not to do it. This happened again in the room before, when a non-player character asked if they should run away. You will get a prize if you tell him to run.
Life Thread Accessory

When you start the game as Sir Victor, you’ll be in a hall where you can talk to three important people. When they tell you who they are, you will have to decide what to do. If you give the right answer, you will get a helpful item to have early on.
The Life Thread item makes it much more likely that you will get a critical hit. This is perfect for Sienna, who already does a lot of damage, to do even more at the beginning of Penalty Kick Online game. This is one of the few early items that you can miss if you don’t pay attention to the conversations.
Sky Armours Are A Nod To Xenogears And Evangelion

You could say this about any video game with a mech, but when you play some parts of Chained Echoes, you can’t help but think of Xenogears and Neon Genesis Evangelion.
In Chained Echoes, some of the color changes you can make to your Sky Armours are called ADAM. Some of the names of the mechs in Evangelion are shown here. Also, these Sky Armours look a lot like the mechs in the video game Xenogears, but the similarities aren’t as obvious.
Termina Caves

One of the first places you go to in Chained Echoes is the Termina Caves. Did you know that the word could refer to two very different games?
Chrono Cross is the sequel to Chrono Trigger, but it’s not as well-known as Chrono Trigger. In Chrono Cross, there is a town called Termina, so it would make sense for Chained Echoes to be referring to it. It could also be a nod to the game The Legend of Zelda: Majora’s Mask, which has a town called Termina.
