Pokemon, but also primarly everything on the GameCube meant a lot to me growing up. I still to this day have nostalgic feelings for the gamecube.
Pokémon (mainly Mystery Dungeon) -> only started playing the core series in Grade 5/2013 don't judge Mario (on the Wii, Nintendo DS, GameCube e.g. Mario Party series (ah the nostalgia), Super Mario Sunshine, Partners In Time-I stopped playing this game because that time I was too young and some parts scared the hell outta me :/) Kirby (Amazing Mirror (I actually ALMOST completed the game but stupid 3 year old me went and deleted the file and I had to replay it so I'm left with one mirror shard ffu-), Squeak Squad, Canvas Curse) c: EDIT: Club Penguin :3 EDIT 2: Super Smash Bros Brawl (played it when I was 6, almost completed Subspace but the effin maze is just impossible :c ) Also, I have played more but there's so much it's impossible for me to remember all the titles.
GTA San Andreas Need for Speed Sly cooper Runescape Habbo I've never liked Mario or anything like that.
Pokemon Diamond Super Mario 64 DS Pikmin (even though this game made me stressed) Legend of Zelda: Phantom Hourglass
Here's my list: GTA San Andreas Pokemon (Gen 1 and Gen 2) Xenosaga 3 Persona 3 and 4 MapleStory Combat Arms Club Penguin Dragon Fable (Anyone remembers this?)
