Welcome!
As @Logain said, the question is much more what would be entertaining for you in a sandbox.
There are several sandbox out there, with many "shared" mechanics and some unique stuff, as you can see. It is about your preference and play style!
@Pluto This could be really interesting to implement.
I'd really like to see some Necromancer bosses that could revive you as a skeleton, but (imho) only a few bosses should be able to do things like this. And maybe when a boss revive you as a skeleton it can mind control you. Or can't?
Also, this "revive a skeleton" option could be something also related to players.
It could be useful to revive your friend as a skeleton for a while to help you kill some monster after he dies. Well, at least if he decide to help you.
Good news! Grats to the winner & keep up with the good work.
I will wait for more news 
@Forcedchaos Hello! We also hope to try the game out soon Welcome
Grazie! Veramente un ottimo lavoro!
@Gothix I voted for a small settlement, but I also like to build in a solo or couple of friends in a isolated area. That could be a "really" slow settlement 
I won't like to build in a large city, but it could work for example outside a large city.
@Gingershadow welcome!
"Fractured Space" is a bit different from "Fractured", since one is a team space combat game (Fractured Space) and one (Fractured) will be a mmorpg
