### 5/5 — Legend

*2026-08-10*

I would recommend all games by the developer, this develop must be a 1980~ generation who has deep mind

### 1/5 — Tutorial is Broken

*2026-08-03, version 2.3.4*

I’m trying to play the game but I don’t know how to, tried to open tutorial but it crashes and closes before I get in, I will fix my review once the issue has resolved

### 5/5 — Suggestion

*2026-07-04, version 2.3.2*

Make a spectator mode to see the ai play it would be very interesting to see how they play, and last suggestion is make the ai a bit less harder because they expand their nation too fast

### 1/5 — Nice background music

*2026-04-15, version 2.3.0*

What a CF of junk on an iPhone.

### 1/5 — 5th ruleset is confusing

*2026-04-13, version 2.3.0*

Good game, but the 5th Ruleset is unplayable for me - why aren’t Civ borders displayed?

### 5/5 — Game crashs - fixed

*2026-04-02*

First try, App crashes - Support reacted fast and helpful

Thanks

**Developer response:** Thanks for the feedback. Would you like to send the saved file to me to let me investigate the reason? Tap … on the load saved game screen.

### 3/5 — Figuring it out

*2026-03-22, version 2.2.9*

It’s hard to get info even in the encyclopedia, I’m trying to figure out how to connect cities across water and I know it was mentioned but I couldn’t go back, to actually read and understand how to do so. But it’s been fun so far, i been playing civ 4  and the actions are similar which makes it easier to play

### 1/5 — Ads

*2026-03-13*

The app has ads popping up everywhere

**Developer response:** Thank you for sharing your feedback. We understand that ads may affect the experience. The subscription removes ads entirely and also includes unlimited funds as an extra premium benefit.

### 3/5 — Tolles Spiel aber…

*2025-12-13*

Das Spiel macht sehr viel Spaß. Leider kann ich bei mir nur den 2 Regelsatz spielen da der andere immer dazu führt das die App abstürzt. Vielleicht wird das ja noch behoben. Wäre klasse. Wenn alles geht würde ich 5 Sterne geben

**Developer response:** Thanks for the feedback. Would you like to tell me which ruleset can crash the app? Or can you send the game saved file to the developer to investigate it? Tap more on the loading saved files UI.

### 4/5 — Great game

*2025-12-08*

A very fun experience with a lot of in-depth systems.

My only issues with it are the use of leader names of other nations and the spelling of Kyiv-Rus’. When other nations talk to you about wars, it shows the leader name rather than the country or the flag. It would be clearer if it showed the country’s name instead.

In regards to Kyiv-Rus’, it uses the Russified name of Kiev-Rus’. It should be Kyiv, as this is the correct translation of the city Kyiv (Київ/Keeyiv).
