So it's like starmade?
Starmade, Corneroids, and miner wars 2081 had a child.
Actual physics system like corneroids, ease of building like starmade, it will have mining ala miner wars and such. Ships fly more like actual ships and require thrusters in each individual direction unlike starmade. The graphics look amazing and meld together perfectly to remove the cube look. I imagine the mining is going to be largely cannibalized from miner wars seeing as the asteroids are literally the same as the miner wars roids. The crashing physics and destruction is seriously great, considering how early in the game is.
Once the game gets fleshed out content wise it will be (in my opinion) way better than all three.
