Did the game launch already? As far as I know it didn’t, and the only publicly discussable version of the game is the Technical Stress Test and whatever Microsoft has officially released on streams, promos, etc. Nobody in the public knows what the final game will have
I know that video is off-topic in that it’s not talking about pop count limit, but since it’s used as an example of apparent dev failings: just because the Xbox website ‘revealed the hotkeys for AoE4,’ it doesn’t mean the game won’t have non-AoE4 options at launch, or that the grid system is the only choice, or that we won’t be able to customize hotkeys/grids/etc. in AoE4; nor is it necessarily a complete and comprehensive list of what the final game will have. In fact, the note in the upper-right says:
For all we know, this could very well take you to a screen that has multiple preset options, similar to AoE2:DE where you can choose between the new “DE” version of hotkeys, or the old “HD (2013)” version, or customize keys until your heart’s content.
So, for AoE4, even though that Xbox website says, “Age of Empires IV Hotkeys,” it doesn’t mean the game won’t include AoE3, AoE2, or other hotkey presets. Maybe it’s like if AoE2:DE posted a screenshot of “AoE2: Definitive Edition Hotkeys” with no indication of other hotkey sets that are included with it. The statement is still valid, and it gives no indication that other hotkey sets exist, yet here are AoE2:DE’s choices:

I’m not saying AoE4 will have other options, but I think it’s a little presumptuous to assume there won’t be any other options and to write the game off because of one screenshot or Tech Stress Test that doesn’t necessarily give the full story. Unless they show screenshots of the final UI showing no other choices exist, then any claim to say devs aren’t giving what players the ability to play how they want is just pure conjecture at this point. That goes for hotkeys, imo, as well as Population Limits. We, simply, do not know what the released game will have or what their post-launch plans are
