Something I'd like to do in multiplayer is to have a group of people and build a whole city. Not sure the LOD complexity can be handled though, but I think of... 2nd life in space.I'm still holding out hope that they will make some changes to the way base ownership works, and allow shared base ownership (and hey while we're dreaming - carriers) between at least 4 people. This is really the make or break feature for me as far as multiplayer goes. Otherwise, yeah I'll probably reinstall at some point but I'm going to give up on it as an online game because the multiplayer just isn't fun when you can't freely share and pool your resources to build something together ala Minecraft.
And uh . . . with all the new space interactivity, a flight model revamp can't be far off, right? Right? . . . guys?
Also, I want more space stations in space, not just planetary things. Elite does have more of a true star-system feel with the stars, planets, and stations. NMS is very poor when it comes to the things in the sky. Rich on land, but not much up there.
Multicrew in some bigger ships. NPCs walking around and doing things in capital ship. Having to make sleeping quarters. Maybe have access to engine and repair, do things there. Have full access to the frigates. And more...
Big wishlist.
