It's an amazing game. It really pulls you to the limits of your strategy and knowledge when it comes to building and warfare. The texture, the mechanics, and others are just so well nice. The only reason I rated it 4 is because there are no walls! We can't establish a define territory and enemies are keeping on going near settlements. I just hope there be like a great wall of sorts to establish territory and borders

Thank you for your feedback and good suggestion! If you change to the diplomatic map mode it will be easier to see what is your land and what is the land of the other factions. Good luck with your future campaigns!

This game is not even though I haven't got to play it properly yet because it keeps bugging, when I max zoom out it bugs and gets stuck, I can't swipe or click UIs, and when I exit to restart, the song still plays even though I'm in the home screen. Good game, and I know it has potential, the ratings proves it, just fix the problems and it's done

An amazing RTS Strategy Game, although you need to understand some things to play well, over all its an amazing game, i love how you can create a city, mobilize its structures, strategize how to defeat your opponents, and create countless army compositions. its a very great game with such detailed precision, i would recommend it if you're trying to find a game like RTS, it really lives up to its genre.
