Warlords 5 theories

I wonder what Warlords 5 would look like if it were to be developed today, and whether such a game would even stand a chance in a crowded gaming market where there's already oversupply and careful filtering is necessary to avoid wasting time on shoddy titles.

Personally, I think the concept of training leaders for individual games, like in Warlords 4, was unnecessary, and Warlords 3 remains the most playable title today, albeit with poor UI. And the UI is not very clear and inconvenient, first of all, for example on the units you can't see how much each of them costs us to maintain each turn, although it was already in Warlords 2.
