“Overall I am really enjoying this game. It's definitely a spiritual successor to the Caesar series by Sierra and I enjoy the challenges! If you enjoy Caesar (by Sierra) Roman city builder and combat then this game is an…”
“Not a bad game. Sand box relaxed for me. 2026”
“Really great game. I bought it because it looked promising and I like the general setting of it and I'm so happy I did. I played a lot of other city-building games before but none of them actually got me that hooked.…”

“A more sophisticated version of the classic Caesar III with many more features and controls. Any Caesar III fan should try it, miss the great music from Caesar III but the music in this one still gives you the vibes!!”

“Fun but very rinse and repeat regardless of the mission you are playing or region you are playing in. It would be nice to have some variety in at least the look of the buildings depending on region, but not even that…”
“Fun overall and the perfect game if you are craving good old Caesar III but the gameplay seems a bit too repetitive for me to sink serious hours into this game.”
“6.5/10 Ehhhh... I feel mixed about this game I'd understand it if it was early access, but it just feels... Incomplete? Maybe i missed something, but it just feels like it wants to be many things at once, but it lacks…”

“This is a fun game so far. Just finished the first mission. Some issues are not readily apparent as to the solution. I use AI or a Google to get more information. I got burnt out on Civilization as I've been playing the…”
“I enjoy city builders. Picked this one up and gave it a try. Lots to like. Lots of things that can be improved on. For me, its very difficult to make money. Every city I have built has gone bankrupt. No biggie because I…”
“This game is OK... I will recomend it if you get it for not much. I have done 50 hours... And in my opinion the game taps out at 50... Earlier for many other people. only 6% of people have done all the missions and only…”

“Spiritual successor to Zeus. Love it. I'd wish the NPC's would talk when you click on them, like in Zeus.”

“It feels very much like a Caesar III sucessor. Excellent game to scratch that itch.”
— a player, Steam review · 7 hrs played“I disagree with the negative reviews from old timers. I'm a life long Zeus fan. I appreciate Caesar, but I prefer Zeus. This is a blend of Zeus and Anno, with a sprinkle of Caesar, with UI from Farthest Frontier. It definitely feels like an indie game, not AAA, but it's not that…”
— a player, Steam review · 12 hrs played“Very interesting. Nice compromise between city builder and clasical RTS. Better than many new AAA strategy games.”
