So ... the wonderful game where the main lead is Moses (Chris Bale) who crushes on the Princess (Diana and Charles, William and Kate - young leaders around the Queen marrying into noble blood) as the betrothed, chosen one of the Queen.
Why is it so REAL? Because we live in the age where Prince Harry, son of King Charles, wanted to do like his ancestor in a movie The Voice and renounce his duty to the throne. In this game, however, the duty thrives and is the main strength and life long dream of our protagonis - when you are that driven by nighthood and total devotion to your Queen (United Kingdom, Commonwealth, other terrytoriae willingly bending the knee to the Queen - life in today world) - the game gets the rollercoaster vibes because this is the way where honest devout adoration for your Queen and country cannot fail, throwing the good times your way.
