I really liked The Outer Worlds, but it lacked ambition. They basically went for Fallout in space, but space was just a few different areas on different planets in a game that was maybe 20-30 hours long, but it was definitely a good start. I think if Starfield can give that sort of fundamental Fallout-ey experience and add actual space elements (like the space combat) and proper open world, it'll be exactly what people wanted. The Outer Worlds was surprisingly polished on release, though, whereas this will probably be a buggy mess.
I don't care for the base building, though, feck that shit.
