The games that have made me, instilled things in me, taught me, created memories and experiences that I still remember...!
Ordered roughly by the time each game most impactful in my life... (except for a few I'm unsure about, and others I remember coming before and after others...! I did my best!)

I love a bit of everything, though somehow Strategy, Sports, MMO, Simulation, Fitness, and Fighting seem to be some of my blind spots... (Though I have a few played in each category, like Pokémon Conquest, Mario & Sonic, Animal Crossing, Wii Sports and Skullgirls!)

To again quote Quintin Smith:
"The very best videogames in existence leave you with a whole mess of memories that are so varied and entertaining that you can leaf through them like a photo album...."
