I think the best improvement for me would be a better diplomatic system.
A more sophisticated diplomacy system could deepen player interactions beyond the simple alliances and warfare we have now.
Imagine negotiating complex trade agreements, forming temporary coalitions against common threats, or establishing cultural exchanges that benefit both parties within the game. That would be something!
Think about it. Players could hire specialized mercenary units from their aloes and civilizations they have an agreement with. This could help them add new strategies and strategic plans to their military campaigns.
This new system could also feature dynamic relationships that evolve based on actions like in other games. For example, breaking an agreement could result in long-term consequences, while honoring commitments could help build stronger and lasting partnerships.
Such an approach could result in a diplomatic arrangement that is more complex and dynamic, which, in my opinion, would better align with real historical contexts.
