This is the game I've always looked for. I DO NOT have to join a guild to play. It's slower to build but doable. I DO NOT lose my entire progress when I get raided. A raid costs the production of only one building. I DO NOT have to spend real money to progress in the game. Everything is achievable with time and patience. Interaction with other players is as much or as little as I want. This game, for me, is perfect.
