I will try to shed light on these few points I found being discussed and which are rather incorrect to be honest. Here it is:
1. The discussion about "LOLOLOL KNF COULD KILL GMG WITH THEIR NAVY" is completely ridiculous and absurd. Nothing of the sort will ever happen, because like it or not GMG and Kusari rely on each other, thus it is totally pointless to discuss about who has a bigger military potential.
The KNF allow the GMG to police their own space, as well as the eastern part of Honshu - this puts far less strain on the KNF and they can send more forces to the war with Bretonia, ergo allowing them to have the upper hand in the war.
2. Deuterium is heavy water. Most earth type planets in Sirius are fairly abundant in it, but the Zoners simply decided to sell their supply. H-Fuel is actually contains Deuterium itself (check the commodity infocard if you don't believe me), so you can hardly say the Zoners are making "competition" for the GMG by selling it.
3. The GMG are *not* the sole provider of all fuels in Sirius. They are the provider of H-Fuel, which is a very potent mixture of different particles that can be used for a plethora of applications. Quoted from the infocard:
Quote:A mix of elemental hydrogen, deuterium (H2), and helium-3 (HE3), H-fuel can also be mixed with oxygen in fuel cells to provide water (via "cracking") and electricity for small ships, space stations, and other facilities.
The GMG have a stranglehold on the fuel market due to H-Fuel's potency and cost/effectiveness ratio. That doesn't necessarily mean everyone else is at the GMG's mercy, but rather that they have to spend considerably more on ship fuel, thus making their space journeys more expensive.
Rheinland's Mannheim station is making H-Fuel in small amounts, not nearly enough for the Rheinland fleet though - and it also brings a loss to the Rheinland economy each year, the Rheinland government is frankly looking to close it.
Samura is trying to get into the market by synthesising their own H-Fuel in Hokkaido, but the lackluster amounts of usable gas (likely Helium-3) as well as constant Blood Dragon raids (financed by none other than GMG) make that enterprise cost more than it is worth.
The rest of the houses mostly buy from Kishiro directly or by proxy. The other factions either raid the fuel shipments, buy it from the Junkers or use other fuel sources (like MOX, or simply pure Hydrogen).
4. There is no rumour in the game that mentioned Rheinland boarding Naha during the 80 Years War. A few parts of my article on the GMG are unfortunately based on logical speculation due to Microsoft's oversights in faction history.
At any rate, my vision of the 80 Years War was based on a successful Rheinland blitzkrieg across Sigma-13, in which they indeed managed to take the Gas Miner Naha, but were unable to operate it due to GMG sabotage and lack of their own experts. The GMG forces would use the Sigma-19 and Honshu jump holes to conduct raids into the depths of Sigma-13, fighting a guerilla "hit-and-run" war for the majority of the conflict, with a few large offensives and indecisive battles spread inbetween. Rheinland's own efforts to build a gas miner (there should be a wreckage of a Kruger station in the nebula in S-13) would be wracked by GMG raiding parties. Eventually in the fall of 668 AS the GMG would launch another large offensive into the cloud, knowing that the Rheinland Military has been stretched to it's limits. Naha would likely be taken back during then, and the rest of the RM fleet would converge at the New Berlin jump hole in the Yanagi nebula only to be annihilated and beaten to New Berlin by the GMG. This would mark the end of the shooting war, the peace treaty would be signed a few weeks later.
That I believe corrects the uninformed points in this thread. As to GMG being a sovereign house? No, it most certainly is not. That does not mean however that it does not own territory, because it does.
