I'm only going to list the things I actively use for gaming because I'm a tech hoarder and the designated hand me down old useless give tech to hand me down person and if I listed everything I would look crazy.
✴ 2DSXL
I had an original 3DS that I got for my birthday, it was preowned from Gamestop. 2 years later the 3D slider broke so I couldn't turn it off, so I thankfully was able to get a new one. I realized last year that I could've use parental controls to turn off the 3D, and didn't need to get a new DS. I still think the upgrade was worth it though. I sold the original 3DS last year.
My favorite games on the 3DS are ACNL, Neko Atsume, Tomodachi Life, and the Ace Attorney Series. I also play my DS games on here (my DS broke when I was 5 or 6, when my toddler brother somehow RIPPED IT APART with his BARE BABY HANDS). My favorite DS games are Cooking Mama and Pucca Power Up.
✴ Playstation Vita
I love my vita to death, I used it basically every day in Middle School. Granted it was literally just my Persona game playing machine but it was worth it because I spend those years obsessed with Persona 4. Everyone would ask me why I had a PSP and I would say it's not a PSP but wouldn't elaborate further. My favorite games on it are Persona 4 Golden, Persona 2 Innocent Sin, and Persona 4 Dancing All Night!
✴ Playstation 2
I got this fairly recently to play some games that I grew up playing at other people's houses (I didn't own a ps2 growing up). I only have 3 games on it right now but I wanna expand that. I have Persona 4. Persona 3 FES, and Dragon Ball Z: Budokai 2. I got Persona 3 for my brother to play on it, I played Persona 3 Portable and was satisfied with that version of it. I want Winnie The Pooh's Rumbly Tumbly Adventure.
✴ Xbox One
Honestly I have no reason to have this anymore but I do have it. So I'm adding it. My favorite games I have on it on Catherine and South Park: The Stick of Truth. Both of which I play on Steam anyway. This console was a KILLER media machine when I got it though.
✴ Playstation 4
Was technically my brother's but I still had my games for it and when he got a PS5 he gave it to me. My favorite game on it is Spiderman PS4, then Persona 5 and Persona 5 Royal (which I rate about equally).
✴ Wii U
I love my Wii U to death and I've been defending it since it's release, I remember being in class and my teacher asking if she should get her kids a Wii U or an Xbox for Christmas and I was the only one very loudly making a case for the Wii U.
My favorite games on it are Splatoon, Mario 3D World, and Nintendo Land. I also play my Wii games on here, my favorite Wii games are Wii Party, Wii Sports Resort, and Wii Fit. I'm literally the Wii U plug and I bring it in a backpack so me n the homies can play the best party games ever released.
✴ Nintendo Switch
I'm soooo conflicted on my Switch because on one hand I love it, and on the other hand I'm disappointed by it. I feel like I haven't really enjoyed playing on it since 2019. I have a Animal Crossing Edition Switch that I got for my birthday in 2020 which I'm really happy with.
My favorite games on it are Splatoon 2, Breath of the Wild, and Mario Odyssey. I also like project diva because it forces me to not waste my arcade credits on the miku machine by telling myself "there's miku at home play a different game, play the wacca machine"
✴ My PC
I recently have mainly been playing games on my PC, because I more and more have been primarily been playing Indie games and playing games in a Discord call with my friends. I use Steam and Itch.io, my favorite games on Steam are Stardew Valley, Dont Starve Together, Lethal Company, and The Wolf Among Us. My favorite games from Itch.io recently are Democratic Socialism Simulator, Pumpkin Panic, Death and Taxes, and Butterfly Soup 2 (Which I STILL need to finish I love Butterfly Soup).
✴ Honorable Mentions
My phone, I love Mystic Messenger and Miitomo (I miss Miitomo)
My macbook air, Whiskey (application) is awesome and I can play my Windows only games on my laptop now.
