I have been working for 4 years on my design and it has grown and changed a lot, while still being true to the core vision. Lately, it has seen simplification (4X games are never simple), and a play-test with my “partial-gamer” wife was very successful. She liked it and is happy to play it again.
4X games “look scary” because there is a lot of stuff on the table but I have done my best to streamline the game down and while “long”, it is engaging all the time with very little down time.
As for when I would like to complete the game, for me it is still at least a year away. I hope to get it into TTS so enable more people to look and give feedback on the game and to save games in progress.
