This may get buried as I am not a typical AOE player… so I probably have opinions counter to most of the people on this forum.
I feel like AOE4 lacks personality. It is absolutely a sequel to AOE2, not AOE3. However as someone who has been playing AOE3 consistently since 2008 (give or take) I feel like it did away with all my favorite parts of AOE3. Instead it fed the (admittedly much larger AOE2 fanbase)
Also I can only speak to my experience of the AOE4 stress test, so I am sure more features will be added at some point…
But I miss the personality of the AI, the taunts they would give. I miss the home city shipments that made it feel like you could really build out a unique and custom strategy.
Even the UI which seemed dated to some, I feel as though it practically defined AOE3. The brown wood grain is what I think of with AOE, not this ultra clean slate blue. I don’t want the assassins creed animus animation effect when a building is created… this game is not magical or fantastical, it is all about going back in time and reinventing a civilization.
I think AOE4 is going to bring a lot of players over… it has a lot going for it, I will be playing it when it does come out. But I am going to miss AOE3. It will forever be this odd anachronistic outlier in the AOE franchise.
