A rare diamond of a game in the current market! This game is truly free and has no ads or micro-transactions, which is super rare for a game of this quality. It's obviously a passion project and very addictive, with tons of stuff to do and high replay value. I had never played the Civilization games, so it took me a little while to figure out what was going on here, but after you get the hang of it, then the game becomes very engrossing and fun. The graphics are simple but sufficient.

This is the best mobile game out there in my opinion. It's based off my favorite game but doesn't cost anything and doesn't have any ads. Also, it is just nice to see an open source game because those are so rare in the mobile world. Apple really prevented the open source community from getting big into making apps due to the apple store. It's refreshing to see a truly open source android app someone just shared because they felt like sharing just like the many open source desktop apps out there

Great game to pass time! The game is a bit hard to learn at first, but once you get the hang of it, it's really fun! I see some people complaining about the difficulty, but that can be easily changed via custom civilisation start points on the map maker, or you can just change the difficulty to settler. There are no ads/microtranscations, and the game is honestly a really pleasant experience! 5/5 stars!
