PART A: DESIGN A WORLD 

If I were to live in a fantasy world, I would live in an open world where I am the protagonist who will save this fantasy world from corruption. This world would be known for swords where every character would be a swordsman or blacksmith. This is somewhat similar from the anime, Sword Art Online. In order to beat the game, there is a tall tower that has 100 floors and each floor would have mythical beasts. Once I've defeated all the beasts, I'll eventually fight a boss. The bosses would get harder each time I level up and reach higher floors. The boss in the 100th floor would obviously be the hardest boss. Once I've defeated the 100th boss, I will receive many achievements, and a special reward. I can still play the game if I defeated the final boss. I can roam around the world and help villagers or other swordsman or blacksmiths. This fantasy game can be an online game where you can group up to 2-12 people in one party. The more people I have in my party, the harder the monsters will be. As I'm the protagonist, I have a health bar, a stamina bar, and an energy bar. There is a daylight cycle where the time runs the same as the real world. That means I need to live like a normal human by sleeping, eating, and resting. If I start a new game, I start as a rookie who has no experience yet and start off as a level one. There are special quests, and if I ever succeed the special quest, I receive a sword. The more swords I collect, my level would increase. The highest level a player can ever get, is level 1000.  If I die from this game, I would lose all my things in my inventory. The only way to keep my stuff, is to keep them in my base or home. This game would be called Swords Infinite.
