Games with multiple factions to choose from

Hi guys,

I am looking for games with multiples factions/races/nations/sides to choose from. More diverse - better. (think of Civilization where differences are only bonus-oriented and cosmetic, and Endless Legend , Warcraft or HoMM where each faction has different play-style and features).

I want a game where there is a point of playing again with different faction "just to feel it", even if you know mechanics of the game already. Again, in Civ after playing one game you pretty know how it is gonna be with different nation. But in game like Endless Legend it is worth to check several races as they have different story lines, different special mechanics, different visuals etc.

The genre doesn't matter (most likely it is gonna be a strategy though), it could be from any year, I am open to play in oldies as well as far it will run on Win 10 and is still playable today.

What I AM NOT looking for is a game where there is high degree of modifying your faction. Unfortunately many space sims are going this way by having few races where you can modify visuals of your spaceships etc.

Visual difference is at least minimum. I don't care if there is a text-based or numer-based game with 100 nations which I can't even see. Ideally: visuals, different tech tree, mechanics, victory conditions.

Here is the catch: I have played in many games in my life. I know most of bigger titles and probably I will know most things you will recommend me. So anything less obvious would be extremely welcoming.

First games which come to my mind: - Paradox's games (Europa Universalis, Hearts of Iron, Crusader Kings, Stellaris etc.) - Blizzard's games (Starcraft, Warcraft) - C&C series, - Age of Empires, Age of Mythology, Empire Earth, - space sims: Galactic Civilizations, Masters of Orion etc.
- Warhammer, - Total War, - Dominions series, - Original War, Earth series, Company of Heroes, Sudden Strike, Blitzkrieg, Men of War,
