From what I know, (I think) Jokupelle makes the game alone unless he has a team with more people now, but it would be cool if you tried to make another game instead of having only one that you update sometimes. For example, it could be like a game related to this one but instead you can play against players and ai where you control the countries (Kind of like the roblox game: Rise of Nations) or maybe completely different from this game. Other than that, great game. I can't wait to see what you will do in the future.
Also, I was trying to word this better, but I couldn't because sometimes I am bad at doing that so sorry if it sounds like I'm putting pressure, or I desperately want to you to do it because I don't want to do that and I have no control over it.
Edit: If anyone wants me to say it better, I will try to. I know that you have 2 games other than this one but I don't know if you are still working on them and I haven't seen you talking about them or at least not anymore on any place.
