If you have room for a wheel well get one my friend.
Space is not an issue. But I won't put it in the living room, where my couch is facing the TV (more a big monitor), and I want to keep a PS4 there, for me, my son and his buddies (he can plug is Switch too), for video games or Netflix and that kind of stuff. And I don't have enough space there to have the couch and some kind of rig for the wheel, even if it is easy to move around (plus I won't have storage space on that floor if I want a rig that can be moved).
So there is no way around using another room if I want to get a wheel.
It also means that I need another PS4 for GTS, not that complicated, second hand are not too expensive.
Yet it will be an issue when GT7 will be available, PS5 is not easy to find, and quite costly, moreover if you need 2 for the reasons mentionned above.
I'll need another screen too. (4K or FullHD... for a future PS5 4K would the way to go, but I'll want another 4K for the living room 😅 )
I also need some rig to set up the wheel.
I could use my desk but it is mainly intended for work, I don't wan't to install the wheel and pedals when I want to play and remove then after. (And I'll need some space to store them between sessions, not a big issue yet I don't have a solution atm).
Plus my desk chair is dumb, the wheels have brakes that do not interfere when the chair is loaded, but block the wheels if no weight. It is absolutely not convenient, to move the chair when you are not seated it won't bulge, and when seated it floats around on the least side force applied by a foot for example (with pedals it would not be possible)
So the best solution is either another sturdy desk in another room (plenty of space in the attic) or a real sim rig, or a homemade rig (I like to make stuff so I know where I would go).
And I am not speaking at all of the steep learning curve when going from DS4 to wheel...
So a wheel is something I dream of, but when confronted to reality, it is not that straightforward without even looking at the overall cost ☺️
