Endciv is available as Early Access on Steam!
Since the release two updates have been made. Before you consider to buy the game at its current state you should make sure that a number of features are not yet implemented and some bugs can hurt your experience. You should take a look at our Roadmap or the recessions on the Store page.
Important to note is that the game has no save games yet and most of the mechanics can be encountered after an hour of play. Everybody is different and some have more fun than others with this version.
Nevertheless I hope you keep following Endciv and add it to your wishlist. Updates come frequently.
