Hello all! I thought it would be an amazing idea to list all the references from past games we have found in Chained Echoes. Here are all of the references I've found so far (off the top of my head):

Chrono Trigger:

★Opening scene
★Glenn!
★Festival with mini games
★Farnsport music (even has that iconic snap in it)
★Visible encounters
★Encounters take place on the map (not an encounter screen)
★Position of characters/enemies based on how the encounter was initiated in reference to the enemy
★The Sewers
★Visual style of areas/the world

Xenogears:

★Gears
★Reincarnation

Final Fantasy:

★Adventurers Guild (Clans from FFXII)
★Unique Monsters (same, from FFXII)
★Loot (Loot from FFXII)
★Deals (Bazaar from FFXII)

I'm still in act one so I'm sure there's going to be a lot more I haven't found yet. I think this is a good starting basis though!

Edit: I'll fix the formatting once I'm back at my computer.
