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.
YMMV: Final Fantasy Dimensions
Ensemble Darkhorse: A portion of the fanbase has latched onto Barbara. Let's count the possible reasons — Dragoon (which are always popular), Action Girl (only the thirdtime these two have been combined), Stripperific, redhead (again, one of the few with Refia and Cissnei), and she has the advantage of her tale being the first of the game to be announced, so she got much more exposure and attention than subsequent characters.
Game Breaker: The Fusion Ability gives you many techniques to try them out on bosses.
