Imagine yourself as the World President in 2100. We have powerful massive weapons. The first FTL (faster than ligth ships) and cyberenhancements. But the Earth is overpolluted and all must die in less than a decade if you didn't found a place to move half of world population. Then your more brillian scientist say you that are a hope. That they created a portal to a new dimension, the pokemon world, as they say that the fauna and the alternative humans must be harmful. So you decide: the death of Earth. Try to negotiate with the natives or erradicate them in cruel bloody war?
