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: Lufia & The Fortress of Doom
Awesome Music: The normal battle theme. Most SNES JRPG normal battle themes tend to be slower, more uneventful, but this game's normal battle theme is a lot more upbeat which makes normal battles a lot less boring when the theme playing in the background is so nice.
Narm: Guy proclaiming that he's "Over 100 years old and still kicking!" only to walk ten feet and keel over is perhaps a little funnier than it should've been.
Scrappy Mechanic: Instead of being able to target individual enemies, players have to target groups of enemies instead, and the party will just attack enemies within that group at random. This makes Wolf Pack Bosses far harder than they need to be.
Also, if a party member is set to attack a group and that group is wiped out before their turn comes, they'll just swing at the empty air and waste their turn.
Tear Jerker: If one plays this after the second game anyway...
That One Boss: The quartet of Demon Lords and the trio of Goblins that are fought early in the game. If the player were able to target individual enemies (see Scrappy Mechanic) then they'd both be relative pushovers, but because you can't they're two of the hardest boss fights in the game.
