Personally I really don't mind te emptiness. I still had that itch to explore and find a.bunch of stuff and I often stopped the car just to get a treasure or an ingredient that I saw on the mini map.
Honestly Liede reminds me a lot of the Okanagan Desert back when I went there a few years back. Vastly empty, only a few places to see and explore, otherwise it was a desert. Mind you, I still expect similar emptiness in the other regions, but I honestly thing this isn't a problem.
I do honestly think that because we only had the main scenario and some hunt to do, it feels even more empty than it will feel when the game launches.
Idk I guess what I'm trying to say is that I like it
