Mongoose
There was a novel a while back called Split Infinity which was authored by Piers Anthony. This World is modeled after a world in that novel called Phase/Proton, to simulate this world requires two game systems, one of which is Mongoose Traveller, the other will use Dungeons& Dragons 3rd Edition. The following is the beginings of a dual system character sheet:
Red is D&D stats and black is Mongoose Traveller
I got this idea after looking at the character sheet in the back of the Core Rules e-book, it uses a bar chart to represent the 6 characteristics of Traveller, so I got the idea of using bar charts in a 2 RPG character sheet.
A word about Proton, the Traveller RPG World
Proton 0123 A67683(8/1)-F
Proton has a class A Starport
Size 6 9,600 km world with 7-tainted atmosphere,
and 6-60% hydrographics,
a population of 8-hundreds of millions
a self-perpetuating oligarchy for a government
Law level is 8 for "offworlders" and 1 for "citizens",
and the tech level is 15
Proton has a dual caste system, they consist of Off-worlders, who are not necessarily born offworld, and Citizens who are effectively the nobles of this planet. The main export which drives the economy of this planet is Protonite, which is a form of metastable hydrogen locked in a mineral found on this planet. Protonite is stable until it reaches a temperature of 4000 k, at which point it reverts to monoatomic hydrogen which then quickly converts to its molecular form, and if it does this in the presence of oxygen, it then combusts into water vapor releasing a lot of energy in the process. Protonite is a useful form of energy in protonite reactors, which convert protonite into hydrogen, and in starships the hydrogen can then be fed into a starship's jump drive to initiate a jump. So protonite is both a convenient form of both energy and hydrogen, this is mined on the planet Proton and exported for a lot of wealth, creating an OPEC cartel like atmosphere. the planet is ruled by an oligarchy of citizens who are the minority of the planet's population, about less than 0.1%, the rest are non-citizens called "Serfs". The serfs have few rights, the usual punishment for a disobedient Serf is banishment from the planet. The "serfs" are here for employment, the wages are fairly high, the biggest threat to a "serf" is that he will lose his employment and be expelled from the planet.
The planet Proton has a dual nature, there is another aspect of this planet called Phase, which is not really a planet but a self contained pocket universe where the laws of physics are somewhat different, in essence, technology relying on explosive release of chemical energy, electronics, or nuclear reactions does not operate, in its place is magic. (In which I'll use the D&D magic system for this example). Each citizen and long time resident of Proton has a counterpart living on Phase, it appears that each molecule of protonite is quantumly entangled with its phasite counterpart, the protonite-phase entanglement creates the pocket universe called Phase. An insubstantial curtain winds its way across the landscape of Proton and Phase, those who's counterparts have been killed or otherwise have died, can perceive this curtain and cross through this curtain into the alternate world, otherwise its invisible and cannot be used to travel to the alternate world.
On Phase no technology greater than 2 operates, gunpower, gasoline explosives burn slowly so as not to create an explosion or operate an internal combustion engine, steam engines do not operate, metals don't conduct electricity making electronics impossible. radioactive elements become nonradioactive and non fissionable, as if in the presence of a nuclear dampener and so forth. A sun appears in the sky, a pattern of stars appears as it would have appeared over Proton if its atmosphere wasn't polluted with smog and haze. The sheet does the coversion between D&D 3rd edition and Mongoose Traveller, it is only partly finished at this point. I will present more finished versions later.
