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.
Hype Backlash: John Romero pretty much hyped the game up so much that there was simply no possible way that it could ever live up to the expectations he was setting, even if it didn't turn out to be an Obvious Beta. It didn't help that he never stopped hyping it during the entire two years that it was delayed.
On top of that, Half-Life came out along the way, succeeding at everything that he claimed Daikatana would do.
During his Let's Play of the game, Proteus4994 admits that the first three levels in ancient Greece, and weapons like the Eye of Zeus and the titular sword are actually pretty fun (or at least much better designed than the first episode and its weapons).
Memetic Mutation: "John Romero is going to make you his bitch.", "I can't X without my buddy Superfly!" and "Thanks John".
Upgrade your jumping ability at all, and every jump you take will be accompanied by the distinctive sound from The Six Million Dollar Man. Remember too that late-90's FPS games were all about constant jumping.
Polished Port: The Game Boy Color tie-in game released by Kemco somehow managed to be better received that the PC game it was based on. Sadly, it only came out in Europe and it was completely different in playing style to the original. However, John Romero put a link to the ROM on his site, so, fortunately, there should be nothing illegal about emulating it.
Porting Disaster: The Nintendo 64 version had blurry, low-resolution textures, and lots of fog to hide the shorter draw distance. The titular Daikatana was removed as a usable weapon. Mikiko and Superfly were removed from the gameplay (which actually makes the game more fun, but still) but remained in the cutscenes.
Even the original falls prey to this: Many of the bugs were caused by a shift in engine mid-production.
Scapegoat Creator: The team that worked on Daikatana apparently consists of only one person - his name is John Romero. According to most people; he did all of the designs, all of the publishing, all of the marketing, all of the debugging, and as a result got all of the criticism. This is ignoring how many people worked on the game, and how the level designs were actually done by Romero's girlfriend, for example.
Still, considering he was taking most of the credit, perhaps it's just Laser-Guided Karma doing its thang.
Scrappy Weapon: So many. It's telling that one of the better weapons is the one that empties six consecutive shots every time you fire it, just because it's one of the few weapons that isn't easy to kill yourself with.
