With such object I'd spend the rest of my life gaming.
I will reduce the possibility of meeting anyone in the future including possible soulmate so I can become a sigma male.
Few days later in the future I will be struct by lightning but end up ok and gain access to a pocket dimension room with a wide sofa, a table, a fridge, a blanket, a door to the bathroom, a light switch, a big TV screen and a gaming set including:
A console that has unlimited storage, unlimited memory. It can run and has all the video games from the past to the future.
A PS5 gamepad with unlimited battery.
A black keyboard with neon light.
A Logitech wireless mouse with unlimited battery.
A pair of gaming headphones.
The fridge also has unlimited amount of any food and drink I desire and the food is always hot. A black hole trashcan would be useful, too. On the same day everyone will forget about me and every evidence of my existence will be gone.
I will spend the rest of my life playing games like Elden Ring, Ghostrunner, Sekiro, GTA 5, Cyberpunk 2077 and many others. I will bid farewell to my first-person life simulator and become the immortal gamer.
