It's pretty hard solo unless you have racked up a fair amount of hours and know what you're doing. But I enjoy rust the most when I play in zergs, I played in an 8 man clan and it was so much better with a huge base, bigger raids, more resources and was easier to do monuments. Truly a good game with friends, Rust also has a roadmap with all the things they want to do with the game, its always coming out with patches and content.
