Now, I’ve never played Space Engineers, so my analysis is likely to be off.
But from what I saw in that trailer, it seems to be kind of like Garry’s Mod contraptions and physics in an emphasis-on-building medieval world [kind of like our Stonehearth, anybody?]. Definitely something I’m going to keep my eye on.
In that trailer, I saw two (presumably) players. Perhaps someone more knowledgeable on this subject could answer my questions. What’s the point of building a castle without anyone but you to live in it? Will there eventually be large multiplayer servers or NPCs to resolve that potential issue?
