Since i can't seen to contact the author directly i'm just gonna post here.
In short i really like the simple core rules of The Rule of 5.
After i'd read the game i realised that while the "backround" was vague to the point of utter irrelevence ( with the exception of the Control Gloves - liked them loads ), the rules could easily be adapted to simplify various systems, both rules and backrounds, into a very neat and workable framework.
The two that came to my mind straight away were the Warhemmer 40k universe and a world/system taken from the D'N'D Expanded Psionic Handbook.
I'm going to do these up myself anyways and i'll probably post what i feel works for me at a later date - and if I could get more info on how those Control Gloves are supposed to operate i'll be very much obilged.
