Single Proposition: Welcome To Corneria

CON

The name is a reference to Final Fantasy I and Eight Bit Theater, both of which are very well-known, at least among the RPG fans who would be reading about this RPG-specific trope.
You don't need to understand the Final Fantasy reference in order to understand the name
Broken Record Dialogue doesn't reference Final Fantasy 1

PRO

Assuming that even most RPG fans would recognize a throw-away line from Final Fantasy I is major Fan Myopia
Corneria is also a Star Fox reference (and beyond that, made it into Super Smash Brothers as a level, further increasing the amount of people who would think Star Fox upon seeing the name), so Corneria doesn't fall under the One Mario Limit.
While the Final Fantasy series is one of the best-known RPG series even made, Final Fantasy I is nowhere near the most popular entry in the series, and thus the popularity of the series as a whole cannot be used as justification for the popularity of the original game.
None of the towns in Final Fantasy I were particular memorable, further increasing the likelihood that the first thought will be of Star Fox
In some versions of Final Fantasy I, the town was actually called Cornelia, meaning that not even everyone who played that game will understand the reference.
The current name makes the trope sound more limited than it actually is
