Conspiracy theory has always mention of Illuminati. Indeed it existed, however its existence ended mysteriously in the past. It is said that their society is so powerful that it controls over the world. World events happened due to their plans and doings.
A pope was even under them, Pope John Paul II was also called the black pope. He holds a bent cross used by satanist in the sixth century, why would a holy man hold such a sinister cross. There is also an infamous hand sign which many world leaders have used without a specific meaning on their actions. Even celebrities showed these hand symbol for no reason.
The all seeing eyes, an eye on top of a pyramid is seen everywhere. It is the symbol of illuminati. It is all over the media as well. It is even seen on the US one dollar note. Illuminati also known to be the cause of the 9/11 incident. President George Bush planned it with the leader of Al Queda, Osama Bin Laden. Many think that such alliance is impossible, however we can see that Osama's father is actually one of US best weapon supplier, which is also Bush's good friend. Many US president is actually members of illuminati. Those who are not and planned to go against them were assassinated. Such examples were Abraham Lincoln and John F.Kennedy.
Alternate world is a world beyond our realms, a world in another dimension, a parallel world. It is said that a world exactly same as ours existed. However, all that existed within that world is a complete opposite of ours. For example, if you are a male, in that alternate world, you would be a girl.
These alternate world or the secret world under our world created through conspiracies is a recipe for great game storyline. Alternate world is usually a fantasy type of genre, while conspiracy is usually an investigation or first person shooter game.
