I just can't go back to the conventional space 4X games, like StarDrive 2. Colonize/conquer a planet, then queue up the build orders for a string of planetary improvements. Nothing's changed in that formula since Civ 1 in 1991 (24 years ago!) and I'm thoroughly bored of it.
And "oh, this planet has a population of 4, 3 of which are farmers and 1 is a scientist." Eh? Way too abstract for me now. In DW, I'll have a planet of 4.6 billion assorted alien races, which generates all sorts of output, which I can amplify with wonders, but I'm not going in there and building "a factory" or "a farm". DW:U feels like I'm simulating running an empire, whereas the old formula makes it feel like I'm playing a very abstract boardgame. And the way DW:U handles the difference between interplanetary and interstellar travel is perfect (though obviously difficult to translate to a turn-based game).
As I said in another thread, DW:U has spoiled me, I can't go back to the old way now. I hope DW points the way for more developers. Even if not, there's always DW2.
