Particularly about
Phantasy Star I that I just love, are the quirky sub-characters you meet and converse with. In this way, I would say that PSI is my favorite Phantasy Star game, because it has those memorable quotes and situations.
My favorites, for instance, are:
The bums who ask you to spare a cup of cola. If you say yes, they give you information. Otherwise, they call you a tightwad.
The guy in the gasmask warehouse who pretends to be the clerk.
The lying dezolians with the accent (conversely, I missed this aspect in PSIV).
Dr. Luveno's assistant who always says, "Don't bother me. I'm busy."
The robotcop who says with menace, "You are a fool! You will DIE!"
The secrets shop clerk in Scion.
Dr. Mad.
The jailed people on Palma.
The guy in Paseo who will trade your laconian pot for Myau, but askes you first if you'd spend billions of meseta for him. If you say yes, he calls you a liar.
