Pokemon Blue was my first video game ever and I still have some painful memories.
When you first start the game I had no idea that to exit the house you have to stand on the darker patch of ground (which I later learned was a doormat) and press down because I assumed that would mean walking into a wall. Two hours later, I finally exited and found the lab and Oak was not there, so I left and explored the town then went back and he still wasn’t there, so I left my character sitting in the lab waiting for him to return and I’d sometimes run back home but only quickly for fear of missing the professor, and it took 5 hours for me to try leaving the town. I hadn’t acquired Flash before Rock Tunnel so I navigated the entire thing in pitch black (and back then you didn’t even have a circle of light). I got so comfortable with the slow pace that when I got the bike and zoomed forward I got so scared that I never used the bike again. It took me months to get into Saffron because I never thought to get something from the vending machine for the security guard to drink so I wandered around for ages trying to find things to do—I’d even wait just before his line of sight to see if he’d turn away. I used only one Pokemon to fight (my starter Bulbasaur) for the entire game so I beat the league with a level 80-something Venusaur and only used Razor Leaf every single time and when that ran out I used leech seed + solar beam. I used my Master Ball on a Snorlax because it took me so long to get passed his blockade (recall how long it took me to get through Rock Runnel) and I thought he was the ultimate Pokemon.
