Yeah. I don't have performance issues but the game feels empty without mods. It's kind of hard to explain. There are only a few trees for decoration for example. Houses are half floating or do not connect to the road when there is a small hill. But I have confidence that they will sort it out.
That being said. Games that are not ready for release should not be released, period.
If you did not enjoy the first one I doubt you enjoy the second one. Tldr: its more in depth than the first one.
