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: Enchanted Arms
Crowning Moment Of Awesome: Early in the game, Ooka destroys a bridge you needed to cross, prompting every player of every RPG to think "Damn it, why can't I just swim across? Why do I have to go arou- Holy crap! I can just swim across!" The Game Designers get a CMoA.
Atsuma and Karin get one in every fight for killing giant robots by punching and kicking them really hard.
Game Breaker: Relatively early in the game the player can access a Casino which can be used to quickly generate unlimited funds, and thereby stats, as well as high level Mons Golems and abilities that make the next few bosses a breeze.
The secret Golem Omega has a move that reduces any enemy's HP to 1, even the final bosses. Combined with a supply of full-EP items, the final bosses can be ridiculously easy.
Ho Yay: Very prevalent among Atsuma, Touya and Makoto, and to a much lesser extent Raigar. The game also seems to go out of its way to make the female characters unlikable in order to reinforce it.
Yuki falls into this...but there's one other reason that becomes obvious later on.
