In an interview at X019, Age of Empires IV creative director Adam Isgreen revealed that the game will have several new features to help new players get familiar with the gameplay mechanics. Age of Empires 4 will have Art of War-style missions to help you and it will also include analytics-based tutorials. Basically, the game engine will analyze your gameplay and will offer suggestions if it notices that you aren't using certain elements of the game.
In an interview at X019, we asked Adam Isgreen if AoE4 would be a good jumping in point for new players, and how it would be accessible to them. “There’s a lot of things we’re doing,” Isgreen tells us, saying he unfortunately can’t reveal too much yet as “a lot of it pivots on the things we’re doing around campaigns. I will say that we’re doing something completely different that’s never been done in an Age game before, or – I can’t think of another game where you can do what we’re doing for campaigns in Age.”
A trailer for Age of Empires 4 was released last month. It's unknown when the game will be out.
