Can I be the first to say:
NNNNNNNNNNNOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!
I guess the writing was on the wall considering the game has been in development hell for many years, but I still look back at the original announcement trailer and think about how cool this game could have been. It was essentially sold as Minecraft but better - with proper combat, better exploration, powerful dedicated modding tools, and more. It was to be created by the creators of probably the biggest Minecraft server ever, which meant they understood the ins and outs of the game and what it needed to improve.
What a shame. At least we got Vintage Story.
Noita and Exanima are also two great explanations of when to make your own custom game engine: when nothing else on the market does exactly what you need your engine to do.
