As a new player I am probably restating an issue that has already been brought up many times however the cargo management hurts my brain. The most glaring issue is the fact that a standard unit of cargo is a ton and this is used for determining cargo capacity. The problem here is that a ton is a unit of mass not a unit of volume its fine to simplify the cargo system to use standard units but those units need to make sense for example a standard unit of cargo should not be a ton but rather a measure of volume such as m^3. Mass is not really a factor in determining cargo capacity of a space craft operating in deep space. Obviously a over mass ship will have crappy acceleration consume a lot of fuel and have a reduced frame shift range but the max tonnage doesn't determine how much cargo can physically fit in the cargo bay or how much cargo it can move between space stations. Max tonnage is only useful in determining wether a space craft can operate within a gravity well. as for a ton being a standard quantity of cargo when you add variations of gravity into the equation a ton of cargo on planet A could be a half ton on planet B or 3 Tons on planet C making this attribute unsuitable as a cargo capacity unit. Optimally the cargo should have both a mass and a volume because not only does this allow for better balancing of cargo capacity it also allows for ships transporting low mass cargo to not suffer speed and jump penalties for a full cargo hold while also making sure lower quantities of heavier cargo will effect speed and fuel usage appropriately as well.
