Thanks for the share! Looks like it has a lot of potential. Looks like a creative guy like me would have a LOT of fun building. I'm only a bit familiar with space engineers so I do not know it in-depth, but I wonder how moddable this will be?
One thing I'd love to see, more than combat perhaps, is town-building and industry. This would really take city-building games to the next level... The ability to create something akin to what Life is Feudal has. Kinda. Moreso all the different industries that are intra-dependant. Though needing NPCs to create a vast city/village. What didn't sell me on that game (Life Is Feudal) was the customization or lack thereof.
One thing that scares me though, especially as an architect in games like these, is how easily those walls crumble! It's as if they didn't use mortar at all! Just a bunch of stones standing on top of one another. I'd hope that changes, at the least.
