So, Why Is Military Trade So Popular?

[Vaimen]

Left, Right and Centre you can see arms or weapons being sold, designed or funded. Some nations are just naturally rich, others are trying to militarise but my biggest question is;
Why is armament so important to countries?

[Togeria]

Mainly for defense or expansion.

[Noctenos]

Defense, expansion, and pointing at people/groups who don't follow your orders. Nukes for the safety of assured mutual and complete destruction.

To answer this as quickly as possible: Humans, like other animals, love war in one way or fashion. Therefore, that behavior leaks here.

To answer it from a GE&T standpoint: It isn't hard, depending how you do it anyways, to make an arms storefront. Though I don't honestly wish to call storefronts that just list some stats and a picture an arms storefront - they are the primary examples though, which is sad. There are other popular ideas here but arms are the most simple and sought after industry to run as. Even I got into it because I wanted to try my hand at it - the only reason im so successful, though, is hard work and dedication to the game.
