Animation Age Ghetto: This was a factor in the game's commercial failure. Rare was reportedly worried that it would be mistaken for a kids' game because it looked so cute and "cartoonish". So they limited advertisement for it to nighttime TV and made the M-rating on the box extra large. This backfired, and the game sold badly due to Invisible Advertising.
Author's Saving Throw: For Live & Reloaded, once the single-player campaign is complete, the ability to uncensor dialogue in the multiplayer is unlocked.
The laser room right before the Final Boss. Berri just deactivates them all, making it completely pointless.
Crack Is Cheaper: Its status makes it one of the priciest games to pick up second hand. There's a reason why most playthroughs are done on emulators. The game was a lot more expensive than the majority of other N64 games, and more than a lot of then next gen titles for the Dreamcast and the PlayStation 2. This was because of the bigger cartridge hardware the game needed, namely so all of the voice samples would fit.
Crosses the Line Twice: The whole game might as well count with its Vulgar Humour but specific examples are the Great Mighty Poo wanting to put Conker's body into "his butt". Another example is Berri's death. She gets gunned down in cold blood, and then her body is sucked out of an airlock.
The Great Mighty Poo. Ties in with One-Scene Wonder since his appearance is brief, yet he's the most well known character in the game aside from Conker himself. He sings, in a marvelous voice, an aria (with three movements!) about how he's a giant poo. And it is awesome.
Some DA fans also consider Batula as this, as he has gained a small fanbase.
Gregg is also popular with the fans, both because of his appearance and because of his funny dialogues.
Faux Symbolism: When the game begins and Conker gets drunk, he exits the bar and walks to the right (where his adventure will begin); in the stinger when he drinks away his depression and gets drunk once again, he exits the bar and walks to the left.
Hilarious in Hindsight: The Nintendo 64 was often criticized as a "kiddy console" with Bad Fur Day being the exception that proved the rule. So when a remake was planned for the Xbox dubbed Conker: Live and Uncut, people expected to see Conker's foul mouthed antics in all their uncensored glory. Cue Executive Meddling and the game being ominously re-titled Conker: Live & Reloaded. The final product was an even more censored version of the N64 original. Some fans certainly enjoyed the irony.
Idiot Plot: The whole Panther King storyline. It took a scientist to figure out that there was a leg missing from the king's table, and even then, the only replacement for the missing leg the Professor considered theoretically viable was a squirrel.
Though on rewatch bonus and with a bit of meta analysis; Conker's Bad Fur Day actually uses this trope quite cleverly. The whole point of the Panther King sidequest is not to help the King fix his table; but rather to buy time. The red squirrel hunt is a fetch quest devised by the scientist to keep the Panther King distracted while the scientist's own Tediz were being built and allow his monster time to grow.
The unveiling of Young Conker for the Microsoft Hololens was met with much ire and bile.
Conker's surprise appearence in the Project Spark Gameplay Trailer received negative reception by fans, especially those whom were waiting for a sequel.
Jerkass Woobie: Conker may be a greedy, sociopathic alcoholic who is willing to kill to get his way, but it's hard not to feel at least a little sorry for him by the end of the game when we find out that Berri, the one person he truly loved, was murdered by Don Weaso (and then he blew the only chance he had at bringing her back) and that he was forced into being the king of the land (which he didn't want the role of), both causing him to be depressed.
Mainstream Obscurity: Many gamers recognize the Great Mighty Poo song, even though the game itself only sold about thirty thousand units.
Nausea Fuel: The entire "Sloprano" chapter; its whole gimmick is taking Toilet Humorto its utmost extreme. Besides being set around and inside a mountain covered to the brink with crap, one puzzle involves swimming through a room flooded with cow manure (which you made by tricking a trio of cows into drinking prune juice) and pushing a giant ball made by a dung beetle into a switch to access Bats Tower. And then there's its boss, The Great Mighty Poo, one of the most revolting abominations ever conceived for a video game—it's a giant mountain of singing poop that eats sweet corn and throws chunks of itself at you!
Padding: The wasp's second attempt at stealing Mrs. Bee's hive is just a slightly longer retread of one of the first subchapters in the game, and it adds absolutely nothing to the story.
The Xbox port, Conker: Live and Reloaded, beefs up the graphics considerably, rescores all of the music into a higher quality format, and includes almost all the voice samples from the original game without compression. Unfortunately, the tradeoff is that all of the swearing was censored (in the original game, only the harshest swears like "Fuck" were censored) and is impossible to turn off, some content was cut out, and throwing out the original multiplayer modes for a new one that isn't considered nearly as fun.
The Rare Replay port is a straight port of the original game, completely uncensored and with almost no changes made save for some slightly awkward edits (removing the entire game intro due to the Nintendo 64 logo joke, replacing "Nintendo Presents" with "Microsoft Studios Presents" in the opening cutscene, and changing the button prompts while the original button prompts are still mentioned by Conker in-game). And while the graphics aren't updated, they do look crisper than they do on the original Nintendo 64 hardware. Also worth noting as that the game has fewer framerate issues than it originally did.
Rated M for Money: This was Rare's intention with the game after the backlash of the original prototype.
Sidetracked By The Golden Saucer: No one's complaining about the single player campaign, but the original game also includes a bunch of surprisingly fun multiplayer modes that are all available right out of the starting gate, and they are considered just as fun, if not more fun than the main game, and being an N64 game, it supports four players off the bat. In fact, when Live & Reloaded only included one of the modes and threw out the rest, it was considered a deal breaker for many fans of the original game.
Special Effect Failure: As astonishing as the graphics and general presentation were considered to be at the time, there is a brief moment in a cutscene where Conker escapes from the Bullfish where he is clearly running on thin air. Since it's only visible for half a second, it's unlikely it was purposely put in for Rule of Funny.
The post-boss scene in Barn Boys called Frying Tonight where you have to focus both on swimming to high ground and cutting down live wires with throwing knives lest you get electrocuted while swimming.
Barry's Mate, if only because falling means doing the whole thing all over again.
Sunny Days is one of the most frustrating parts of the game due to some serious Fake Difficulty. After having to backtrack back and forth all around the barn area to find all of the bees you need (one part involving some tricky platforming on the barn's water tower), you're treated to the challenge of having to use a sunflower's breasts as a springboard to reach the money on a ledge up above. The controls for this part are not only stiff, but completely unintuitive; you have to jump on her three times in a row in a certain way, and if you do it wrong, not only will Conker be unable to trigger his helicopter tail in mid jump and reach the money, he'll go sailing out of control through the air and take damage when he lands. Making matters worse is the terrible collision detection; you'll more often than not pass right through the sunflower's chest as you try to chain your jumps on it! All of this takes what should have been a ridiculously simple platforming gag and turns it into a needlessly exasperating mess of Trial-and-Error Gameplay.
Bats Tower has a couple segments that are a pain in the ass. The eponymous tower has very thin platforms that you have to slowly navigate (along with ropes that are tricky to grab due to the fixed camera angle), and you have to put up with bats hounding you along the way—you can use a flamethrower on them, but one slip up will knock you back to the ground level, forcing you to trek all the way back up. Later on, you have to trek through a dark underwater safe, which has a labyrinthe design that makes it easy to get lost and drown in.
U-Bend Blues can be pretty tough as well with it's One-Hit Kill rotary fans, Rare themselves even lampshades this with the various Red Squirrel remains that are in pieces that are under the water you swim in.
The latter half of the Spooky chapter, where Conker has to find three keys in a mansion full of zombies and bats, and bring them to the front door. While carrying the key he can't jump or use his shotgun, and he loses the key if he falls or gets attacked.
It's War. As you get further into it, it's incredibly hard not to die at least once when you have to shoot off a giant lock on a door with a bazooka since the game bombards you with tons of Tediz, then even further into the chapter you have to make it back to the boat on the beach while trying to avoid laser walls, the catch? There's a time limit in which you need to get back to the boat quick or the island blows up with you on it, doesn't help you get a slow moving bazooka as your only weapon against the Tediz towards when you're reaching the end.
They Changed It, Now It Sucks!/It's the Same, Now It Sucks!: This is a rare case of both being valid complaints with the remake. In the changes department, a large amount of fans were unhappy about Live and Reloaded being heavily censored despite being Mature rated, cutting out content, and replacing its much loved multiplayer with a new one. As for what it kept intact, the main story had no new content added beyond its updated visuals (and certain select things changed in beginning Hangover chapter, slightly more enemies in certain chapters like more spike imps in certain chapters and added possessed dolls in the Spooky Chapter).
Visual Effects of Awesome: Regarded by many to be the best looking Nintendo 64 game out there. Featuring dynamic shadowing, coloured lighting, large areas with a long draw distance, no distance fog, detailed facial animations, lip syncing, and individually rendered fingers on some characters. The graphics in this game are so good that it could pass off as a very early Sega Dreamcast or PlayStation 2 title.
What Do You Mean, It's Not for Kids?: Some gullible parents bought the game for their kids on the assumption that it was another cutesy Rareware platformer due to the squirrel on the cover, despite Rareware making it very clear on the box that it is M rated and that it is not a kid friendly game at all. The very first screen you see on booting up the game warns you about this too, just in case you didn't get the message already.
