I first started playing with old PC games from the late 90's and early 2000's like Insaniquarium, LEGO chess, Stronghold 2, Jurassic Park III: Dino Defender, Age of Empires II and III (especially II), and some brain train games. I was like 5 or 6. I revisited some of these this year which has been pretty fun and heartwarming, some of them are genuinely still good to this day like Stronghold 2, others not so much but still incredibly nostalgic like JP3.
Then a Wii/DS with games like Bowser's Inside Story, the first two NSMBs, Galaxy 1 and 2, Super Paper Mario, Wii Sports, Wii Sports Resort, Wii Play, Wii Party, Mario Party 9, LEGO Batman 1, LEGO Indiana Jones 1 and 2, and DKCR. I got those when I was something like 6, 7, or 8 and kept playing them for years and to this day many are my all time favourites like SPM and BIS. Though these days to play Wii and DS games I mostly use Dolphin and my 3DS respectively.
I also started playing some mobile games on an iPad that was like shared by my family when I was like 10 and kept doing with various ones over the years (notable ones include the angry birds series, clash of clans (and some similar games like battle beach), jetpack joyride, and the bloons tower defence series) till I got my 3DS though it got a lot less frequent when I was like 13. I revisited a few this year and the later parts of last year via the BlueStacks emulator and my new iPhone 12 but I didn't get back into them much, and I have barely played mobile games in the last month even though my iPhone is one of the things I do have at university.
My brother also got an Xbox 360 when I was about 12 which I played Minecraft on (the x360 version of that game was much if not most of my gaming life age 12 to 15, I got Java Edition when I was 15) and a few LEGO games (lego marvel super heroes and lego indiana jones 2 mainly, later on lego batman 3 and lego dimensions)
It wasn't until later that I got the GameCube (age 15), Wii U and 3DS (age 16), and Switch (age 18) so I won't list those games, though more info
here.
