I was SO excited when I saw the announcement for this - intrigued to see them branching out in to yet another genre. As always the game is highly polished, beautifully executed and is fun to play. The UI is great and they're demonstrating yet again that they can take an existing genre and add their own unique, high quality spin to it. Unfortunately my first thought from the demo was correct - I don't see any replay value. Gameplay in the overworld is an anno clone, and the mining gameplay is great, but can gets repetitive even on the first playthrough. It's a good 8 hours entertainment, but lacks replay value and complexity.
