I HAVE SO MANY!! I've played a little of everything but I'll try to remember my toppest ones!

Nes: Adventure Island 3 (I loved playing this so much, the art style is so cute and timeless)

Snes: Donkey Kong Country!!!!!

N64: Ocarina of Time / Pokemon Stadium / Quest 64 / Pokemon Snap

Gamecube: Tales of Symphonia (I loved Lloyd, Raine, Zelos, and Sheena)

Gameboy: Pokemon Red (I think Pokemon yellow was my first pokemon game but I played Red for hundreds of hours I'm sure)

Nintendo DS: Pokemon SS/HG

Nintendo 3ds: Pokemon xy

PS2: Kingdom Hearts 2

PS3: COD 4 (around this time I was getting heavily into pvp shooters)

PC: World of Warcraft (I played since classic launched), New Vegas, Oblivion, Tainted Grail series (card game + Fall of Avalon), Ruined King, Zomboid, TF2, Arcanum

I mostly play pc nowadays.. I want a steamdeck someday because nothing truly beats holding a little handheld console. I love my switch too, but I'm not dexterous enough anymore to play with consoles. I'm spoiled by mouse.
