There was once a man, not an ordinary man, who went by name GM.
He went to and fro, from hill to meadow, to meet his journey's end.
But there was one, who abhorred the sun, and lurked beneath the sea.
The fickle thing, taking lives yet merrily sings, it's name was RNG.
Two sides of a coin, these two were, foes beyond compare.
For whatever GM did, RNG forbid, and left the players in despair.
Now is the time, to end my rhyme and let you play the game.
But before we start, let's be smart, and teach you all the aim:
You are all collectively the GM, and you must defeat the evil RNG. You have the ability to create whatever you want, but all it depends on the roll of RNG. Make a dragon? Rolled a 1? Nope. Make a sandwich? Rolled a 6? Have fun with your new psycho killer tsundere sandwich. RNG is in his castle beneath the ocean, and you must find a way to breach it. RNG cannot make more of what he already has, but he can reroll each roll he does once.
You can have as many actions as you want, but be warned the more actions you take, the more dice will be rolled, and the dice are your enemy. If you roll badly RNG will hurt you through your own actions. You start with 10 hit-dice, and your initial health will be determined by rolling all these dice. Your maximum starting health could be 60 and the minimum could be 10. All it depends on is your enemy, RNG.
Name your first actions, GM!
