...what can DU take from all of them? What aspects of the competitors should it leave alone?
I apologize if this seems off topic (due to mentioning competing games) but I thought it was fitting because it's still related to Dual Universe and what stuff it could add.
True. For me to compare it, it has to be a game and not a tech demo.
When I bought Space Engineers back in 2012 or 2013 with great joy, I already wished that I wanted to play something like that with more players. And Starbase does indeed achieve that at first glance. DU needs to get a few things right before I even see it as a competitor. The game can't do more than stroke the mutual ego phallus. Where this Landmark in space game can lead is anyone's guess.
