Despite the frustrating lack of info, Distant Worlds 2 remains at the top of my most-wanted list. If there's any one game that can rival -- or surpass -- Stellaris' "living galaxy" feeling that I so crave, then DW2 is definitely it.
The Master of Magic remake is a close second for me. I've always wanted to try this one, but have found the original difficult to get into. And as I have mentioned before, I badly need -- NEED, dang it! -- a new fantasy 4x (even if this isn't "new", per se).
Galactic Civilizations IV is another one I'm keeping a close eye on. Still needs lots of fleshing out -- not surprising, given that they've just entered alpha -- but it shows a lot of promise. It's nice to see Stardock being a bit more innovative with their design this time around.
Not yet announced: Horizon 2. This one has been in the slow-cooker for a few years now; and while I devoutly hope we'll see *something* before Christmastime, I suspect that realistically it won't be until 2022 that we get any real news. I haven't got into the original game as much as Anguille as, but there are definitely aspects of it that I like and/or appreciate, and am very much looking forward to seeing what the sequel brings.
