Systems with only one linked RPG

An [RPG System] is used when the same underlying game mechanics are shared by multiple RPGs. If a system is only used by one RPG then there is no requirement to list that system separately in the database.

This page notes all current [RPG System] entries that have only one (or no) linked [RPG].

Some of these may be appropriate if there are RPGs not currently listed in the database that should be linked to those systems. If you know of these cases, please add an explanatory note in the table.
Some of these may not be required, in which case they may be removed from the database at some point in the future in order to streamline the database contents.

System	RPG	Notes
6-6 System	Alpha Omega
Cinematic Adventures	Hidden Invasion	The original Hidden Invasion rules set, used to distinguish from the Fudge and Theatrix rules versions (Stelio)
D666 System	In Nomine	D666 system is thematically linked to In Nomine; highly unlikely to be used elsewhere, and therefore probably redundant. Worth giving details of the dice system somewhere under the RPG, e.g. 'more info'. (parrais)
Inverted 20	Hot Chicks	Tricky, because it has a microbadge. Bounty Head Bebop is not a part of this system. Apparently there is an admin note about this one, so it is here for completeness.
Middle-Earth Adventure Game	Middle-Earth Adventure Game
Mojo Rules!	Suzerain	The original Suzerain rules set, used to distinguish from the Savage Worlds rules version (Stelio)
The Octask System	The Octask System	Should apply to eight different RPGs from Nightcandle Imaginations. See also: http://stores.lulu.com/nightcandle (Stelio)
Open Core System	Open Core
Renaissance	Clockwork & Chivalry 2nd Edition	May have some others coming out soon
