Self-explanatory. Movies that take advantage of death for time saving purposes.

Examples:
Rygar
Double Dragon 2
New Super Mario Bros.

Used for movies that take advantage of glitching SRAM in some way. This can be done by resetting or suspending a game during the saving process or by taking advantage of a glitch that causes data to overflow.

Examples:
Chrono Trigger
Dragon Warrior 3
Pokémon: Yellow Version

This category should be used when significant luck manipulation occurs. Ideally the luck manipulation is obvious to the viewer. This is ideal for movies where many enemy drops are manipulated, or many critical hits are scored.

Examples:
Castlevania 2
Dragon Warrior 4
Pokémon: Ruby Version

This is used when significant glitches are used that alter the look/feel of the game, change the gameplay, or create significant time savers. Small bugs in the programming do not warrant this category.

Examples:
Mega Man
Super Mario World "small only"
River City Ransom "playaround"
Super Metroid "glitched any%"

Used for movies that aim for the killing of all (or all that is possible) enemies at the expense of fastest completion time. This is an acceptable tag even if the author aims for fastest completion time as a secondary goal.

Examples:
Gradius 3
Gumshoe
Yoshi's Safari

Used for movies that explicitly avoid killing enemies (or only kill as few as possible) when it is unnecessary for game completion, even at the expense of completion time. In games where avoiding unnecessary kills does not postpone completion, it can be used as a stylistic choice and should still be tagged.

Examples:
Contra "pacifist" – delays completion time.
Yo! Noid – stylistic choice.
Silver Surfer – stylistic choice.

This is to be used for "low glitch" runs that intentionally avoid time-saving glitches.

Examples:
Pulseman "no motion glitch"
Super Mario 64 "70 stars, no BLJ"
Sonic the Hedgehog "no zips"
Super Metroid "any%"

A game restart sequence includes pressing reset, power-on, or using a built-in game restart such as pressing a certain button combination on the second controller.

Examples:
The Legend of Zelda
Metroid
Legend of Zelda: Link's Awakening DX
