I like the teaser!
I just fear that the visually inclined people are not going to like dCity. There are two interfaces (the official GUI and command line Cityhelper on Discord) that serve number crunchers well but no developer has bothered to build an interface that is visually up-to-date (which is a shame as they could be easily monetised via market fee share).
We currently need a video to address frontend developers more than players.
