Just a quick look at this had me going "aaaargh !" :

Interesting video, but sadly none were what I would call as "City building." E.g. No new Sim City.
Interesting actually that even though there are quite many projects coming along that there are no sim city style game. I would describe most as Settler/banished or transport tycoon copies. If they bother to make so many retakes on these so why not a classic sim city with a modern twist?
The best building game (not "city-building", mind you) coming out these last few years was and is Banished, for me. A one man endeavour ; then the creator opened his game and batlotters flocked in -- the explosion in custom content is comparable to what happened with SimCity ; and yes, OK, CitySkyline. Although it seems to me that batlotting for CS is not that hard. Am I mistaken ?
