It's not precisely the game I dreamed of building, but it's so damn close I can almost taste it... All those years of Sean O'Neil, Ysaneya, myself, and many others building procedural planet after procedural planet, and none of us had the vision and drive to actually build that.
On the one hand, I'm sad I wasn't involved in building it. On the other, I'm overjoyed that somebody went and built it anyway
You should check out shores of hazeron. It's got every feature no man's sky does (Plus way... Way more), but it's made by a programmer who can't do art at all. All assets are procedurally generated, except the player characters (Which you create).
