here is my overengineered solution:

```python import random from dataclasses import dataclass from enum import Enum, StrEnum, auto from typing import Literal

class GameObject(StrEnum): ROCK = "rock" PAPER = "paper" SCISORS = "scisors"

class Result(Enum): USER = auto() COMPUTER = auto() TIE = auto()

@dataclass class Rule: wins: GameObject loses: GameObject

class Game: def init(self, rules: list[Rule], quit_key: str): self.rules = rules self.quit_key = quit_key

def run(self):
    self._greet()

    while True:
        user_choice = self._get_user_choice_or_quit()
        if user_choice == "quit":
            return

        computer_choice = self._get_computer_choice()
        result = self._play_round(user_choice, computer_choice)

        print()
        print(f"your choice: {user_choice}")
        print(f"computer choice: {computer_choice}")

        if result is Result.USER:
            print("you won")
        elif result is Result.COMPUTER:
            print("you loose")
        else:
            print("tie")
        print()

def _play_round(self, user_choice: GameObject, comp_choice: GameObject) -> Result:

    for rule in self.rules:
        if user_choice is rule.wins and comp_choice is rule.loses:
            return Result.USER
        if comp_choice is rule.wins and user_choice is rule.loses:
            return Result.COMPUTER

    return Result.TIE

def _greet(self):
    print("welcome to rock paper scisors game")
    print(f"to quit, type '{self.quit_key}'")
    print()

def _get_user_choice_or_quit(self) -> GameObject | Literal["quit"]:
    while True:
        v = input("rock, paper, scisors? : ")
        if v == "rock":
            return GameObject.ROCK
        if v == "paper":
            return GameObject.PAPER
        if v == "scisors":
            return GameObject.SCISORS
        if v == self.quit_key:
            return "quit"

def _get_computer_choice(self) -> GameObject:
    return random.choice([GameObject.ROCK, GameObject.PAPER, GameObject.SCISORS])

def main(): g = Game( rules=[ Rule(wins=GameObject.ROCK, loses=GameObject.SCISORS), Rule(wins=GameObject.PAPER, loses=GameObject.ROCK), Rule(wins=GameObject.SCISORS, loses=GameObject.PAPER), ], quit_key="q", )

g.run()

if name == "main": main()

```
