These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ho Yay: It's sparse, though not absent. The Working Designs versions of Lunar 2 make a Running Gag of Ruby willfully misinterpreting Leo's attempts to get Hiro to join him as come-ons. Also, some have managed to interpret Dyne and Ghaleon's friendship as a bit more than friendship.
It's even less subtle in the Childhood's End manga, where Xenobia states outright that "Ghaleon-sama's heart always held dear only one person... a human male..." In the same frame, there's a faded outline of Dyne. Combining that with the intro to Silver Star Harmony, which hints at Dyne/Althena as a Generation Xerox of Alex/Luna and shows that Gheleon is quite devoted to his goddess creates an OT 3. Xenobia's still out of luck, though.
Needs More Love: Lunar: Eternal Blue. The Silver Star has been remade three times and Silver Star Story even got a (Japan and South Korean-only) Windows PC port, while Eternal Blue only got one remake on the PlayStation. While you can still find it if you look hard enough, those Eternal Blue Complete CDs aren't gonna last forever!
Older Than They Think: More people are probably familiar with the PlayStation versions of the two games, without knowing that they were actually playing a remake of two Sega CD games — made at least two years before the PlayStation was released. (Heck, if you were to go by Japanese release dates... the first Lunar remake was at most year before Final Fantasy VII, same with the Sega Saturn version.)
Scrappy Mechanic: Among Dragon Song's problems was the fact that running drained health. If you can get past that, you'll eventually face wave after wave of enemies that can break your equipment. Not fun.
There's also the fact that you can't choose which enemy you attack, the game having each character's A.I. choose their target instead and taking much of the strategy out of the player's hands. Not to mention Combat and Virtue modes, which boils down to having to choose between getting XP from a fight or items. Really, much of the combat system suffers from the designers overcomplicating even the simplest, most basic RPG mechanics.
Seinfeld Is Unfunny: It can be really,really hard for people who got into video gaming in at the turn of the millenium or so to get what the big deal with these games is, and can't really grok the massive leap in production value and narrative complexity that the games represented in their original release (to say nothing of the fact that their anime artstyle was very unique in the West, when they were first released). These games even introduced the Evil Albino to most Western gamers, Final Fantasy VII! Nowadays, the plot elements involved are old hat and animesque games are a dime a dozen, so Lunar's significance can be hard for contemporary gamers to grasp.
What an Idiot: A minor example. Luna, ocarinas and string instruments sound nothing alike.
