First of is that guy supposed to be THE Ramza? He looks nothing like him (plus the story they talk about a second person with Delita, who Im sure is Ramza so if they were talking abuut that other Ramza wouldn't we know? I mean they claimed Ramza (the npc you meet) is 16, Ramza would/should be WAY older.
Also we see Final Fantasy Tactics characters and Robonastre? Well even if I were to believe that FF Tactics and FFXIV are in the same world... Final Fantasy XII takes place 1000 before tactics sooo wuldnt the characters be impossibly old by now?
