I suspect my answer to this question will be a little unique, because of my perspective as a creator: How has a game surprised you?
For me, I’ve never been more surprised than about the fact that people like Era: Survival so much!
I worked hard, as I do on every one of my games, to provide something not seen often enough – pushing it 100 years after the cataclysm, providing a huge array of factions, and creating the Karma system. It’s really caught on, and I am amazed and happy about that.
Era: Survival tried to offer something different and special, and it seems that people really feel that it did!
