Thanks for all your comments! Glad you like the game.
Yes, the resolution is not working below 1920x1080 atm. Will try to address in the next build.
The game is designed to be less evolutionary than Age of Empires, where the goal is more to rush through the ages to get the best units and technologies. I love Age of Empires, and when we started working on the first prototypes of The Fertile Crescent in 2017, this game actually did start in the Palaeolithic age and progressed through ages, similarly to in Age of Empires. However, we're not trying to recreate Age of Empires, and we quickly discovered that the progression through ages didn't fit the type of gameplay were trying to design. So we scrapped it.
The Fertile Crescent takes place in roughly 3500BC-1150BC, when farming was already common. However, you'll find that foraging is always more efficient early game, especially since farms cost resources and time to construct. We give you the option to make farms right of the bat, but it might not be the best option.
There will be more stuff to do than now though! So far, we've only implemented typical early to mid game content of a multiplayer session (and we still lack hunting, fishing etc.), but there's more late-game buildings, technologies and units planned and upcoming. :)
