Syncretizing Gaming Best Practices

I am attempting to syncretize a collection of GM touchpoints from my collection of RPGs and gaming articles. There are so many good resources out there, and I feel I'm swimming in a sea filled with numerous currents, pulled in many directions. I'm hoping to compile a guidance document to bolster my gaming.

This is probably just a fraction of the potential best practices to be gleaned from these games or resources, and I certainly have more items that I could trawl for gems. Some of these do have some bearing on the rules or character creation, it is true, but my ideal is to have a system-neutral skeleton that works for me.

System	Technique	Notes
X-Card	At any time, if any person involved in the game becomes uncomfortable, they can tap or pick up the X card and the thing in progress will stop – no questions asked, no explanations required.
Dread	The Tower	Provide a player with a graceful way out of a game; provide a benefit to the players remaining
Apocalypse World (and other *World offerings)	Fronts, PC-NPC-PC Triangles; Countdown clock; streamlined character sheet	Generate conflict between PCs; get characters up and running quickly
Fate	Aspects, Compels	Punch the player in the Aspects
Lazy Dungeon Master	Numerous shortcuts
3-Line NPCs	Line 1: What the players can see: NPC appearance and what the NPC is doing at the moment they meet Line 2: What to portray: What the NPC does for a living and personality Line 3: How to progress the story: Adventure or encounter hook	Introduce an NPC Every Session Whack an NPC Every Session Think Like/Portray/Impersonate the NPC Crunch Out NPCs While You GM (using a standard array of stat bonuses)
3x3 Method	Relationship Mapping
Location Description Template	Room Type/ Environment/ Status; Obvious Elements/ Subtle Elements/ Hidden Elements/ Backstory Elements	important "clue" elements in each list could be highlighted
