Something that might also be worth looking at is a community cash shop, similar to DOTA2's workshop on steam. People of the community can submit models/designs for implementation into the cash shop - based on vote by the community (coz then you know people are gonna buy the stuff), and DUAL takes a percentage of the share.
These can be things like a variable line of ship designs, or personal items, skins etc. It would be upto to DUAL to set the cash shop categories for such items - and then review popular items that are voted by the community for implementation. I guess it all depends on what you can have on the cash shop.
This is a good way to keep the community active to designing and creating content that DUAL can use for their cash shop. Especially if it's like .... dang.. what's word. stuff that looks good. vanity items?
things like model pieces for your character... bionic arms, robotic legs, etc.
