Hi! Thanks for your interest!
This project is indeed still in the works, and I really want to start full-time on it again. These days I have a full-time job as a software engineer, so I spend most of my development energy there. In the coming months though, I will return to CultGame full-time.
I’m sorry about the lack of updates, but questions like this definitely motivate me to invest more energy. It helps to know that people care.
I, unfortunately, can’t give you a timeframe on release, but I hope to get the closed beta open within a year and then roll out a full release shortly after.
An update I can promise in the near future is that I will have a steam page! Look out for that :)
