Crystalis/YMMV


 * Crowning Music of Awesome: The whole game (at least the NES version) is made of this, but especially the music for Fort Shyron. You definitely get a feel for the residents' desperate struggle against Draygon and his army.
 * Wild Fields
 * Demonic Spiders: Dear Lord, the wizards in the Pyramid Basement right before The Very Definitely Final Dungeon. Not only can they hit you with a spell that turns you into a helpless slime, but their elemental resistances are set up so that you have to take them out With This Herring Butter Knife Sword of Wind. Oh, and did I mention that they have craploads of Hit Points? Good luck getting to the rematch with Draygon without burning through your supply of Fruits of Repun and using all your magic points flying in a (sometimes vain) effort to avoid them.
 * Game Breaker: The Warrior Ring, which enables you to fire off the first level of your charged attack with just a button tap. You don't get it until the endgame, but it allows you to rip through anything vulnerable to a level one blast from the weapon in question. Note that this does work with the Crystalis sword, and, which is a big part of why it's an Anticlimax Boss. Notable that all of the bosses immune to this all fall under That One Boss.
 * This troper has experimented in the final battle with  and found that Crystalis can do that naturally, making even the one level of charge the sword has irrelevant.
 * Goddamned Bats: Bats, birds, harpy-looking things...really, any enemy in the game that can fly. Near the end of the game, you get Toxic butterflies that, upon being killed, release clouds that poison you if you touch them. Once you get the Warrior Ring and armor that has immunity to poison then you're mostly safe, but then the helicopter droids in The Very Definitely Final Dungeon can get you just from the sheer amount of damage you take from them and the fact that they're everywhere.
 * Porting Disaster: The Game Boy Color port of the game, released a decade later, makes alterations to the game mechanics that make things harder than the original, among other things.
 * To some, the complete sundering of the plot to something much more basic and boring is even worse.
 * That One Boss: Pick a member of Draygonian Empire (Well, Kelbesque and Sabera aren't too bad.) The rematch with Mado in Goa Fortress is particularly noteworthy for the same reason Quick Man is noteworthy: he bounces around the room much too quickly to be hit reliably while happily plowing into you in return.
