Love your setup, Kazin.
My main console setup is my good ol' TV with the OLED Switch, PS5, Analogue Pocket, PSTV, and Wii U hooked up (as well as an old office PC in the center cabinet that I use for watching movies and TV). I've been wanting a new TV for some time, and I'm short an HDMI port so I need to get a switcher at some point, but I just this week got a 24 outlet surge protector, so I've got everything plugged in including my controller charging docks. The Wii U sees more use than the PS5 or the Analogue Pocket, believe it or not. The Wii U and PSTV are modded, the rest are stock.
Extra controllers and such mostly get squirreled away in a hidden drawer in my coffee table.
Most of my gaming these days is on my PC, which I bought a few years ago when money was a lot less tight, which is why I ran out of budget and ended up continuing to use a monitor and speakers from 2009. I usually play with the same 8bitdo controller I use for the Switch OLED, but the keyboard and mouse are pretty nice, and there's a special mnousepad under the deskmat that continually charges the mouse wirelessly so that I never have to plug it in. I cut a sheet of corkboard so that the rest of the deskmat feels flush, and it's in multiple parts so I can swap the deskmat out with a smaller one if I want to. The tablet is mostly for drawing and video calls.
I keep my Game Boys and related accoutrements in the bedroom. I don't pull these out as often as I'd like anymore.
I still have my little retro cart with the adorable tiny CRT on it, but it's so heavy that it usually stays in a closet. I may need to rethink a lot of things about my setup. There's a mechanical video switcher with satisfying clunky buttons attached to the underside of the top shelf with command strips, and a huge rat's nest of wires that funnels everything into a single composite cable with mono audio. The Gamecube, Wii, and PS2 are all modded but I haven't gotten to touch the Dreamcast or purchased any Everdrives for the other systems.
Unfortunately, I made a very stupid mistake a few months ago and bought this enormous CRT, which is still sitting on a towel on my living room floor, because nobody even makes furniture that can hold one of these things anymore. It has some red-shifting that needs to be fixed too, but it's probably not worth it to do so. As a result I have an enormous 70 pound cube that I dilligently kick on every morning and Mystery Gift another Ice Berry onto my abandoned Pokemon Silver cartridge. Yes that is a second N64.
What really kills me lately is that I have all these handhelds these days that I want to play more than I do, because I just don't know where to put them when I'm not playing with them. I'm very much a "everything needs a dedicated spot" person and I'm not shelling out $100+ on an official PS Vita dock.
