My custom title says it all "Childhood was paradise"
I do the same, half a year ago I finished GTA Vice City again, Call of Duty United Offensive, Medal of honor allied assault, and played a lot of Max Payne 2 I even bought a used Gameboy Advance to play Pokemon Crystal and Pokemon Ruby, but it just wasn´t the same even though Pokemon Gen 2 and Gen 3 were the best video games I have ever played in my entire life.
I also started Watching the first season of Pokemon up untill episode 47 and watched Yugi-Oh too I miss those amazing years as a child it was heaven on Earth, I just want to go back to my childhood.
Seriously childhood and teenage years is living and adulthood is existing. Childhood is pure happiness all around and teenage years are hell but at least as a teenager there was a lot of excitement in the midst of all the suffering now as an adult I just exist and only experience apathy and anhedonia I want to be a child again so badly! I had a ton of friends, hobbies, passions, life was so amazing stuck in the blissful world of childhood filled with imagination, hope, ignorance and naiveté.
