According to Wikipedia the butterfly effect is a metaphor that encapsulates the concept of sensitive dependence on initial conditions in chaos theory; namely, a small change at one place in a complex system can have large effects elsewhere.
Entropia Universe is a complex system, and the economies in the Entropia Universe are not strictly seperated, changes introduced by individual planet partners like RT will also impact Calypso economy.
With the upcomming Apocalyps at Rocktropia, which promises apocalyptic changes to Rocktropia, primarily on its effect on the RT economy (bootstrapping the economy to make it a viable planet), the anticipated impact on Calypso and other planets economies will be larger than with regular planet partner changes.
What impact do you foresee on Caly economy after the 10th of December?
And are you ready for this? (See also this thread).
