OOH! I have one. I recently played a game called Reigns, it's simple enough, but the story is a potentially compelling one with alteration and expansion. Here's my version (with intro):
One upon a time, a mighty king boasted a grand fortune of such gold, jewels and silks to make any rival jealous enough to kill him, were they not so afraid of his imposing and loyal army consisting of the finest men anybody could muster. However, even these treasures and achievements did not satisfy him, as material wealth and other human notions of accomplishment faded...
One day, a tempting demon approached him and offered something worth all the wealth and beyond, the immortality of the king's memories. Every new king would inherit his memories, the demon advised, preserved for eternity as if they were lived just yesterday. More so, he said, the memories of admiration and aspiration from each new king also remembered so the next may envy him all the more. The rich king gladly accepted, as no scroll or engraved stone could ever preserve his legacy better than the passing on of his very consciousness! The king died happily of old age a few years later, and a successor was crowned. That is when the curse began...
You see, every time a new king was crowned, the memories of the old ones were indeed so well preserved like the demon had promised, but with every fear, vice, regret and even the moment of death vividly remembered, each new king had to bear the burdens of this knowledge while their subjects call them all mad fools for being so preposterous in such an impossible idea.
The game continues with each new king being played through and deaths such as poisoning, violent murder and so on being remembered by the next (since the player reads it), causing each successor to become madder and more melancholic as they increasingly seek to break the curse. The game can also feature kings learning from the predecessor's mistakes instead of the conventional game over (the story continuing regardless) and players are encouraged to actively choose more paranoid options such as refusing banquets and executing close friends in order to avoid regression and nasty deaths, all while furthering the story's main plot to end the curse once and for all.
...
I would be happy to provide further story development ideas and contributions. What do you think so far?
EDIT: Yes, it basically follows the same basic premise as Reign itself, but without the two-option kingdom balancing and a very dark storyline instead of the original silly tone.
