can players (non-faction) own them. I know only curtain factions can use assigned data cards. Just wanted to know; say any type of ship DC can be used at any Shipyard or item/factory...ect.
here is the thing- I wanted to buy a hidden base DC but was told you needed to be in only that faction to build it. True or no?
Every entity that can be produced has a datacard. If you want the exact number, add up all of the produceable entities on the rules pages; they should include ships, weapons, droids, items, and vehicles.
