YMMV / New Super Mario Bros. 1

  • Angst? What Angst?: Mario (or Luigi) certainly doesn't have any qualms seeing Bowser get Stripped to the Bone after the first boss battle; they just say their end-of-boss phrase cheerfully and move on.
  • Anti-Climax Boss: Bringing a Mega Mushroom to any boss will squash them in a single hit. Even the final boss can be defeated in two stomps!
  • Awesome Music:
  • Fridge Logic: Why does Bowser Jr. keep screwing time waiting for Mario to beat each world boss to drag Peach to the next world when he could just run all the way to the last castle without wasting time?
  • Game Breaker: Against bosses, the Mega Mushroom will destroy ANYTHING. Even Bowser.
  • It's Easy, so It Sucks: A lot of people feel this way. Even Miyamoto has stated that he regrets making it too easy.
  • Nightmare Fuel: World 1 boss, when you jump on the button, it sends Bowser down to the lava, then swimming upwards, and burning alive to the bone.
  • Power-Up Letdown: The Mega Mushroom looks awesome, but if you break a pipe, you can't go down it, ruining your chances of potentially finding a Star Coin. Also, the Blue Shell handles awkwardly with its sliding mechanic, though it does improve your swimming. The Mini Mushroom, meanwhile, lets you jump higher and with (much) floatier physics, as well as access certain areas otherwise inaccessible, with the drawback that it has zero hit points; one hit from anything will kill you. When you're going for all the Star Coins and have to use it in the later levels where things get hectic...all those lives you accumulated in the early levels are going to come in handy.
  • Seinfeld Is Unfunny: At the time of release, New Super Mario Bros. was Mario's—and the video game industry in general's—grand return to the 2D Platform Game scene. Nowadays, however, it's often seen almost as rehashed as its successors.
  • That One Level:
    • 8-6. Vertical level with lava rising constantly. And the midway point appears early in the level.
    • 8-Tower 2. This one has you riding a snake block with almost all the way. But there are so many obstacles in the way. But you have to ride the snake block, or else you will die.
  • Win Back the Crowd: Up until the release of New Super Mario Bros., 2D platforming games were mostly relegated to indie PC games. With console gaming, platformers in general were starting to fall out of fashion. 2D platformers were all but dead and the number of 3D platformers considerably shrunk. NSMB was such an unexpected success that Nintendo decided to release a Wii sequel. That one was also a huge commercial success and led to 2D platformers returning to the mainstream in the console market.
