I don't know much about it or if it's still prescribed but I'm pretty sure methamphetamine can be prescribed for ADHD (often under the brand name Desoxyn) in some countries. So I assume it must have some kind of useful effect like more commonly prescribed ADHD medications.
Street methamphetamine would probably be less consistent in effects because it is unlikely to be pure and would probably be cut with other substances so it would be hard to tell what was having what effect.
Minecraft - Was my absolute childhood and I met so many good friends and learnt a lot throughout my time playing the game.
Skate 2 - The controls are perfect, the vibe is amazing, it's just one of my overall favourites.
GTA V - The first R rated game I played. Both this game and Fallout 3 were massive inspirations for me focusing on 3D environments as a Game Dev student.
Honourable mention to Little Big Planet and Rollercoaster Tycoon Deluxe; both of which absolutely shaped my childhood
This reminds me of how I call my to-do list my "list of doom"
