I really love seeing behind the scenes footage of the map tools!
We noted their updates about Rastar in the monthly update, so it's cool that it was expanded on in ISC this week. I like how seamless it makes things, adding location pieces around the landscape without breaking up the existing ground.
No, I think the UI uses building blocks. There doesn't seem to be a whole lot that's different about Rastar that wasn't already covered 2 years ago at citizencon: https://youtu.be/fQkN1YdT6SI?t=491
I think maybe the original outposts were built without using this tool? It's more feature complete now and so they're using it to revamp all the existing bunkers. At the end of the day, nothing changes for the players besides the exterior layout of the area around the bunkers.
Yeah this is sort of a rehash, but the prospect of building a base that's more interesting looking than the current outposts is a pretty cool possibility.
