Super Mario Galaxy/YMMV

A list of some of the Subjective Tropes in Super Mario Galaxy.
 * Breather Boss: Topmaniac, who for some reason gets to guard four stars for being the easiest boss in the game. He also counts as a Recurring Boss (well, to a greater extent than any other boss in the game - even Bowser, who's fought 3 times (the last one's a three-parter, but still), although he doesn't really get any more difficult to defeat.
 * Camera Screw: Mostly averted. The camera is mostly designed to give you the most convenient view when you're on a linear path. The screwing mostly happens when you're in an area that requires exploration.
 * Crowning Music of Awesome: The Gusty Garden and Battlerock themes, among many others.
 * The whole soundtrack. Kondo and Yokota used an orchestra, for goodness sake!
 * Crowning Moment of Heartwarming: The scene where Mario flies with the Grand Star with Peach in his hand.
 * Ensemble Darkhorse: Rosalina, a female character in a Mario game who averts Damsel in Distress. How refreshing.
 * Follow the Leader: Since Galaxy first came out, there has been a large influx of gravity-based flash games across the Internet.
 * Game Breaker: Mastering the game's very loose physics can make the game much easier.
 * Goddamned Bats: Frozen ones, too! They can only be harmed with one hard to aim power-up, and one touch will freeze you for a while. Thankfully, they only show up in one mission.
 * Goddamned Boss: At least three examples: Kamella, Bouldergiest, and Kingfin.
 * Hilarious in Hindsight: The game's title was first used in a fan letter published the December 1991 issue of Nintendo Power. The letter in question detailed a fantasy game system which would come bundled with a game titled Super Mario Galaxy, but would be "better known as Super Mario Bros. 24!"
 * It's Easy, So It Sucks: Some find that the game's greatest flaw is that getting half the game's stars to fly to Bowser is too easy. Getting all 120, however...
 * It Was His Sled: The fact that getting all 120 stars allowed one to play as Luigi became common knowledge shortly before the game even came out.
 * Memetic Mutation: U R MR GAY.
 * U R MI ALY
 * YA I M R U
 * Nausea Fuel: With the gravity and camera angles (you often appear sideways or upside-down), it can get a bit disorienting.
 * Nightmare Fuel: ADMIT IT, you were scared when If you understood the Gainax Ending quickly enough for the repercussions to take you by surprise, that is. Also, YMMV anyway.
 * Kingfin was kinda scary.
 * Also, right before Bouldergeist explodes, his uvula pulsates, his head shrinks, and his eyes triple in size... and he explodes...
 * The NPC bees are cute, but take a close-up look at their faces...
 * The Lumas' cycle of gorging themselves, and then committing suicide by exploding into a new celestial object. They are eventually being reborn somehow, but these guys are happy that they are exploding.
 * Bears a hilariously disturbing resemblance to a certain kinky fetish.
 * That gigantic Electric Jellyfish you first see above your head while trying to swim up and around it.
 * Ruined FOREVER: Bee Mario got this reaction when he was first revealed.
 * Scrappy Mechanic: Swimming underwater is a major pain in the arse. The worst aspect of it is if you overswim your target by just a little bit, it's next to impossible to turn back around without going way out of your way.
 * The Spring Mushroom power-up. You can't stand still while you're wearing it, the movement is very wobbly, and it requires precise timing in order to do a high jump (and unsurprisingly, the areas in which you find the spring require many such jumps). It doesn't help that it doesn't appear until very late in the game, which means you have to use it on some of the harder levels without having a chance to practice using it in easier levels first.
 * Ray Surfing in the Loopdeeloop and Loopdeeswoop Galaxies.
 * Rolling the Star Ball in the the Rolling Greens Galaxy, the last part of Mission 2 for Melty Molten Galaxy, and Rolling Gizmo Galaxy. Even a slight tip in the wrong direction of the Wii Remote has a chance of resulting in complete and utter failure.
 * Using the Sling Pods in the Space Junk and Sling Pod Galaxies.
 * The bubble blowing levels are meant to frustrate you to hell.
 * Pull Stars seem to have been conceived just to torture people. It reaches it's most irritating during the purple coin mission at Ghostly Galaxy, where one must pull themselves past mines and collect coins within an ungodly strict timeline.
 * Tear Jerker: Rosalina's storybook.
 * That One Boss: Beating Bouldergeist the first time is relatively easy. Beating him again with one hit point for the Daredevil Comet Star achieves controller-breaking levels of frustration.
 * The Daredevil Comet version of Kamella is even harder. It's pretty easy to get the first two hits on her, but following her up to the crow's nest without getting hit and then dodging the fireballs and Magikoopas to score two more hits on her requires epic levels of patience and persistence. You can spin attack the Magikioopas to get them out of the way for a bit, but considering that Kamella keeps hurling fireballs at you while you try to do this, it's easier said than done.
 * Fiery Dino Piranha can be incredibly frustrating. Having to time hitting his tail when it's not on fire wouldn't be so bad if you weren't having to chase him/run away from him at the same time. Thankfully, the game doesn't make you do a daredevil run of this one.
 * Strangely enough, one of the most irritating bosses isn't even named. The Mole Gunner in the Toy Time Galaxy can be incredibly frustrating, especially since defeating it all but requires the use of the Spring Mushroom.
 * That One Level: Some of the Purple Coin missions, and especially Luigi's Purple Coins.
 * ANY of the Cosmic Luigi races. Sure, Cosmic Mario's easy enough to beat, since he basically just follows the beaten path, but Cosmic Luigi spams speedrunning tactics like rapid long-jumping and taking extremely obscure shortcuts. Needless to say, if you can beat Cosmic Luigi, consider yourself a master of whatever level you're playing.
 * Bubble Blast Galaxy and that electric maze....
 * The Daredevil Comet mission on Melty Molten Galaxy. Unlike the other Daredevil Missions, this one requires you to play the entire stage, instead of just a boss. A stage mission that's already frustrating.
 * They Wasted a Perfectly Good Plot: Flying Mario. It's only used in one solitary mission back at the Gateway Galaxy, and for easy access around the Comet Observatory. It's only obtained at the point where you can beat the game so it's largely pointless. Worse is that a spin attack from Flying Mario can actually pull nearby purple coins toward you. If that's not reason enough why they should have included the powerup in other missions, just imagine using it in a boss battle.
 * Visual Effects of Awesome: Despite running on ostensibly aged hardware, the game still manages to pack quite a punch in the visuals department, thanks to a fantastic art style and well-done backgrounds.
 * What Happened to the Mouse?: In the storybook, what happened to ?
 * The Woobie: Rosalina in the storybook.
