The system in 'I Created My Own System' is like a customizable RPG menu slapped onto reality. The protagonist wakes up one day with floating screens only they can see, letting them assign stats, unlock skills, and even tweak difficulty settings like it's a video game. Strength, agility, intelligence—all boostable with points earned from completing quests. And these aren't generic fetch missions; the system tailors challenges to the user's environment, like 'Defeat the school bully' or 'Master calculus in 48 hours.' What's wild is the crafting feature—combine a textbook and a coffee maker? Boom, you've got an item that brews liquid knowledge. The system evolves too, adding multiplayer options where others can temporarily gain abilities if the protagonist shares access. No reset buttons though—choices are permanent, which keeps stakes high.
