** The drop rate mechanics in general are widely disliked, due to the fact that you can only get one card from any duel, and the length of the average duel compared to the exceptionally low drop rates for cards means that if you want a particular card from a given opponent, you might need to duel them ''hundreds of times'' before you successfully obtain it, never mind if you need '''multiple''' copies of that card.
** Getting a S/A-TEC rank, which is required to obtain many of the better magic and trap cards from certain opponents, requires you to use a lot of magic and trap cards while stalling the duel, or making the opponent deck out by forcing them to fuse. This is a very involved process that is counter-intuitive to how most people would play the game, as stalling out a game to this degree, especially against the tougher endgame opponents, is very dangerous, as they often have extremely powerful monsters and magic cards that can basically turn around the whole duel in their favor. Many people playing the game casually may not even realize that the TEC ranks even ''exist'' without looking them up, much less how to get the higher ranks effectively. Moreover, with how slow the game plays, being forced to draw until your hand is full, and the player always going first, a single S-TEC duel can take a very long time, even on an emulator. And with the fairly terrible drop rates for most desirable cards, this makes what would already be a very long and tedious grind exponentially worse.
** The [=PocketStation=] features being only available in Japan, leaving it impossible to obtain the cards only available through them, including ''many'' strong AI-only cards and the cards on the cover of the game. This makes the endgame very difficult and unfair, as opponents have access to overall stronger cards than you such as Gate Guardian and Blue Eyes Ultimate Dragon, requiring you to rely strongly on specific cards like Meteor Black Dragon and equips such as Megamorph (which themselves usually require a lot of tedious grinding to obtain) that usually need to be drawn quickly lest you have a strong chance of losing, making an already very RNG-heavy game even worse.

* CultClassic: Despite being infamous for its brutal difficulty (or perhaps because), this game still has quite a bit of fans to this day. It's unquestionably the most popular Yu-Gi-Oh game to this day, to the extent of attracting even people who aren't otherwise into the franchise or card game into it because of its dedicated speedrunning scene.

With how slow the game plays, being forced to draw until your hand is full, and the player always going first, a single S-TEC duel can take up to about an hour to complete even on an emulator. And even if you do everything right, the random drops mean you still might not get the card you're looking for.

** High Mage Kepura is the most difficult of the high mages you'll face, and is as difficult as what you'll face in the endgame, using Gate Guardian powered up by the meadow you duel him on. With an attack over 4000, it'll take just two direct attacks from it to be defeated. If given the opportunity, he'll often equip his Gate Guardian to make it even more powerful. If you takes too long to defeat him, he will summon [[StoneWall defensive monsters such as Wall Shadow or Millennium Shield]] to stall the game [[FromBadToWorse until he draws another Gate Guardian]]. Even the Meteor Black Dragon alone won't gain you victory here.

* FridgeLogic: "Summonned Skull" in this game has two affinity, Moon (the default one) and Pluto. While most monsters who use thunder or electricity attacks in this game have Pluto affinity, Summonned Skull's anime trademark attack ''Makorai'' (lit. means Daemon Lightning) only occurs if the Moon affinity is chosen instead of Pluto.

* {{Speedrun}}: A popular game for speedrunners, as mentioned above in GermansLoveDavidHasselhoff. Notable for having some of the longest speedruns in the entire history of speedrunning--with only games such as ''VideoGame/BatenKaitos''[[note]]Which is, due to a single item, two weeks long. Though most of that time is idling for those two weeks to let the clock run for that one item.[[/note]] being able to rival them in an 100% category. But if you dare to go for ''True 100%'' without trades or duplication, you will have a long road ahead of you, as it is hypothesized to be the longest possible speedrun '''period''', with only True 100% ''VideoGame/AntiIdleTheGame'' coming close to contending with it. How long is it? As [=EZScape=] calculates in [[https://www.youtube.com/watch?v=cL4oV6yqhFA this video]], it would take approximately '''93,396 hours'''. That's 3891.5 days, or approximately 10.65 years. '''''Of gameplay.''''' Even segmented to only playing 8 hours a day every day, this would take over 3 decades of playing the same game, and that's if you don't decide to ''redo'' a segment for any given reason!

** Millennium Shield, while not too much of a problem ordinarily, can greatly lengthen the already-excruciating grind to get your first Meteor Black Dragon. Meadow Mage has multiples of it, and will very often play it with the Meadow field, boosting it to 3500 defense, meaning even Meteor Black Dragon itself can't break through it without help -- and without breaking through it, even if Meadow Mage can't do anything, neither can you. Making matters worse, if you rely on Twin-Headed Thunder Dragon as your powerhouse, its Uranus guardian star over Twin-Heads's Pluto will raise its defense to 4000. Even if you manage to strike it down (only possible with spell or equip cards), chances are that your performance rating for that duel is wrecked, and Meteor Black Dragon can only drop after an S-Power or A-Power ranked victory.
