The Foundation update really improved the procedural generation engine for planet terrain. They look much more natural now. Stunning at times. For walking around exploring landscapes, it's a great chill experience. Space combat is okay, but could use improvements. If you're looking for more than that, I would wait until the next update drops. No one knows what will be in it though. I think the majority of complaints center around there not being enough short-term directed goals, like a job system. The base building added some missions, but in general you really have to make up your own goals as it currently stands.
