Veteran game developer Mark Kern has had a Mech-v-Kaiju game (Em-8ER) in development for a long time now. This crowd-funded game gets backer updates in a public fashion via video updates as well as via their Discord server. It's not going to be on the shelf for a while yet, but just seeing a videogame go from elevator pitch to complete product is a fascinating process. I'm embedding the video for the other day below so you can see for yourself; links are in the video description.
I like what I see. I just hope I have a computer that can run it when it goes live.
