Players of P Club's National Deficit Revitalization Technique

I used to be an ordinary P Club player. By some mistake, I traveled to a different world and got a system similar to the game UI. In order to save this weak country, I must mobilize everything I learned to achieve a great revival of the kingdom. So, am I playing Crusader Kings 3, Mount & Blade 2, or Hearts of Iron 4? (The well-known Hearts of Iron 4 and Stellaris will appear later, and there will also be a TFR line in another world. Now the plot is more related to other P games, Mount and Blade, Crusader Kings 3, and Europa Universalis 4.)
