City of Titans celebrated with fireworks. That might not seem like much until you watch the video and understand that it's the first video wherein every single shot is focused on things that the design team made. The fireworks, the physics effects governing them, most of the buildings -- all designed by the team at Missing Worlds Media.
Previous videos of the game have relied heavily upon off-the-shelf assets and resources that other people had made, but this video is a look at a landscape moving from "designed by others" to "designed just for this game." Obviously there's a long way to go, but if you're looking forward to seeing what the team at Missing Worlds Media can do in the future, this is a good place to start.
