I've been playing this game solo since I purchased it and I'm on my 4th play through right now. This game has filled a spot for me that many other survivor solo experiences hasn't - I can't place my finger on it just yet, but it has a great mix of encouraged exploration, building, leveling, and challenge when and where you want it. The procedural world generation ensures each play through feels unique and adds a great deal of replayability to it. Jump in and give it a whirl - It's not done, but like someone else said, it feels amazingly polished for what we do have.
