Why is everyone complaining about jumping in all the equipment being unrealistic? Who cares, so many things in these games are impossible as it is. You don't see people riding giant Dodo's in the meadows of New Zealand or people casting a ball of fire at others. It's fantasy game, why worry about realism?
Despite the fact that many people fall back on this line of thinking whenever anyone brings up "realism" or "believability" with regard to a fantasy world, it is nevertheless a flawed argument; I will attempt to explain.
"Dodos in New Zealand" are not possible only because there aren't dodos in New Zealand. This simple fact does not, however, eliminate the realism or believability of an animal existing in another world
. Final Fantasy XIV does not take place in New Zealand and, as such, can believably, realistically, plausibly have whatever wildlife or phenomina exist, provided they come with adequate explanation.
Various creatures inhabit the FFXIV world, creatures who, upon the land, likely breathe Oxygen due to the presence of trees, and plants which grow as our familiar Earth plants do. It is a world with air and sky, with weather - an atmosphere as we know it - with water and gravity; most things operate in Erozea as they do on Earth, just with an alternate ecosystem. It is entirely plausible and defensible that different species of animals, be they Lalafel or Dodo, can exist in an alternate world, as they operate according to alternate laws.
Thus, when somebody mentions that "carrying fifty beds does not make sense in FFXI," they are correct: according to the physical laws set in place in FFXI, Vana'diel's forms of matter operate almost exactly as ours do, in that they maintain functionally constant shapes, sizes, forms, and weights and are subject to a seemingly exact Earthen gravity. If matter could
be re-sized in Vana'diel, it would makes sense that such a quantity could be carried by one person, but as it has never been addressed within the world itself, and given all the applicable commonalities with Earth, it is nonsensical that such a feat can occur - and further, nonsensical that stepping over a fence, traveling underwater, and many other similar instances are likewise impossible within Vana'diel.
To conclude, the concept of realism still readily applies to fantasy worlds. If there was no realism, the world would be completely unfathomable, operating by inconsistent physical laws and scattered with matter that shifted without any predictable pattern into shapes we could not even see. Therefore, when someone says that "something" does not make sense within the confines of a certain fantasy world, it is necessary to examine whether said "something" is plausible within the world in which it exists
, not on Earth, where it obviously does not.
