Its not "almost none"… there is no economy full stop. An economy would mean that players could buy and sell armour, weapons, materials, ships, sparrows, etc. and the prices for these would fluctuate based on demand vs stock. That is economy. "Almost none" would imply that there is at least some form of trade. Destiny has nothing of the sort. The game literally has zero economy of any shape or form. I would love to actually see it incorporated though, but it is going to be trick and if put in prematurely then it's only going to cause more problems.
