Saw this video, not sold entirely but I can understand the hype a little better now.
This seems to be a very important speed run site:
Some random Wiki info:
- Any% , or fastest completion, refers to completing the game as quickly as possible, and often involves sequence breaking.
- 100% , or full completion, requires the player to complete the game to its fullest. This often includes collecting all key items or upgrades, finding all secret features, or anything else that may be deemed important. Specific requirements for a 100% speedrun are different depending on the game. Some games, such as Super Metroid , have a percentage counter and therefore have an easy definition for 100%, while others do not, and instead the game’s community decides what the definition for 100% should be. Any% and 100% are the most common categories for speedrunning.
- Low% , or minimalist completion, requires the player to complete the game by obtaining the fewest key items or upgrades possible. If the fastest way to complete the game already involves the player picking up the fewest key items or upgrades, a low% category may not exist for that game’s speedruns. As with 100% runs, low% speedruns have requirements that vary between games. For example, in New Super Mario Bros. Wii , this means no power-ups or Yoshi.
- Glitchless , typically a subcategory of one of the above categories. Glitchless runs, as the name implies, are absent of glitches, but may still allow exploits that do not break the game.
In addition, there can be game-specific categories that change what the goal of the run is and what restrictions are applied. Some runs restrict things aside from completion or glitches, such as Super Mario Odyssey 's “Minimum Captures” run. Such runs are also sometimes called “challenge” runs. In addition to these, games can have categories devoted to goals other than completing the game, a large sect of which being “meme” speedruns, which are dedicated to absurd or otherwise pointless tasks, such as Mii Maker 's “Matt%” and Super Mario Odyssey 's “Nipple%”.
