While objectively a half-baked game in plenty of regards, even without mods, it's still insanely enjoyable.
Start from the bottom, recruit some peasants, get into fights, choose what side you'll support, and all of that just to ultimately create your own country in the middle of all the political intrigue.
Of course, if you don't like the base game, give mods a try. Some of them push the game in a direction you might find more enjoyable.
