I grew up on Civil, since its 1st iteration. Still a fun, dynamic game. However, this app crashes frequently and for no apparent reason. Sometimes after an hour, sometimes as soon as the game loads. I'm still in my 1st run-thru and I've advanced to about 1300 ad and can't finish another turn because its crashed probably 15x. 5 star for the game, -3 star bc it crashes. 2star avg. Only worth it if free, they should really refund everyone who buys it until its stable. Galaxy S9. edit: also, not compatible with my chromebook. cant even download it from the play store
