From the Game's Text:
About my RPG HYBRID: It assumes that reality tries to reveal itself.
About the Author: I'm trying to find an easy way to make sense out of gibberish that is found in many advanced math books, by Rule # 369. And, use that to understand science-fiction that of MU & Dr Who.
HYBRID is an incomplete homebrew RPG that attempts to model a large number of emergent phenomena through a small number of mathematical formulae. The function X^Log10(X) is one of the core parts of the system. The game is mostly diceless, although d6 are used where randomisation is employed.
It consists of many rules (551 in the last version) each of which either states a way to model something using the game's formulae, or is just a commentary by the author (and not actually a rule). Some of this commentary is not directly related to the game.
The game text makes many references to other RPGs. The most frequent references are to the 1986 version of Marvel Super Heroes, Champions / HERO, Aberrant, and GURPS.
