OGame Story
It began in the year 2250 - the year `alpha` - when the first man took the risk of an interstellar flight of more than three minutes and thus farther than any probe had gone before. It was a new kind of engine called impulse engine, which allowed mankind to travel at the speed of light. Yes there were earlier space flights, but those were limited, a mere glimpse into space 
compared to the later achievements. But mankind`s natural impulse for new adventures continued to push the development further and thus prolonging the space flights little by little over the years.Modern engines were using highly energetic deuterium fuel allowing them to travel from galaxy to galaxy in relatively short amounts of time. Unfortunately, this deuterium was very rare, on earth only 0.015% of all water was in the form of this heavy isotope. Later, even the best deuterium wasn`t good enough anymore, and a new scientific debate was born, discussing over new ways to generate an even better fuel than deuterium itself already was. Based on a well known theory, it was believed to be possible to combine deuterium with a mysterious gas emitted by a quasar`s explosion. The quantum-chemical reaction with this mixture would set free huge amounts of energy, so much more that ships could travel faster and faster. Scientist Fred Terrane put his hands together and started to design an engine based on the above theory. Despite the criticism from almost every scientific side, the new propulsion engine finally showed the theory to work - although based on the current level of scientific knowledge, it shouldn`t have to. In real-world applications the new machinery proved to live up to its promises and cultures all around were able to head for outer space even more easily and even faster.Diplomacy was big in these times and there were not many conflicts between races. Until an previously unknown chemical element named 
Xentronium was discovered on a some people`s colony.This chemical element was extremely rare to find, and during the first years after its discovery, only 1.5 micrograms could be harvested. Because it had been found on terran ground, only laboratories of the terrans would be able to investigate on this new element. Xentronium was believed to have the power of 10`000 terran suns per microgram! Once this knowledge spread across the universe, envy and ill will arose from the dark and caused conflicts among the nations which sadly enough ended in a war. Quickly two parties were established, those to the terran fraction and those against the terrans. It was Nostradamus who once saw that the war would last for 150 years, but reality proved him wrong as the war wasted more than 300 years. Thousands and thousands of nations were drawn apart, fell or completely disappeared of annihilation.The side of the enemies to the terran federation started to use some ultimate weapon by the name "omega bomb". As the name already suggests, usage of this bomb wipes out entire parts of a galaxy, freeing it from any civilization. Hundreds of years after the new time system and the year alpha was established, the universe was faced with the most dangerous and most deadly weapons ever created, solarsystem after solarsystem was destroyed and literally removed. Calculations were conducted to predict the outcome: Only a mere 24 years after the first omega bomb was dropped, known space within the universe would be wiped out leaving lifeless space behind...
