Nothing this year. We'll see how 2022 goes.

I purchased some replacement rubber parts to go behind the buttons of my PS4 gamepad, this cost about £2.
There were also two 2TB Hard Drives that I purchased for around £120 or so, primarily to be used for backup purposes.

~ 180€: little more than 150€ for a new tablet and less than 30€ for a 64GB SD for it.

Nothing.
Only hardware I got this year was the Xbox Wireless Headset worth €100 but I used my MS reward points.

Legacy platforms for me this year. I got a Vita in early 2021 and just got a PS3 around the end of the year.
The Vita came bundled with games and accessories and was around $180.
The PS3 only came with a power cord. No AV, no controllers, no games. It was under $90 including taxes and shipping.
So I'm in the $250 and up category.

Zero.

Also €0.

I think 2020 was €0 as well and I doubt I'll get anything in 2022 either.

It's either 0 € or 11.90 € depending on whether you count the external HDD case I got for my extra SSD to use as extra space for my PS4... only to notice that Sony has placed an arbitrary restriction that prevents using disks smaller than 250 GB with the PS4, despite my 120 GB SSD definitely being able to fit a few games. I might have got the case anyway because I've been wanting one for a while, but it would also be fair to count it as 'gaming hardware' in this case.

I bought the Monster Hunter Rise controller for Switch, even though I already owned two previous pro controllers. It meant I could retire my Xenoblade 2 edition so I don't get any more wear on it.

No plans to buy anything this year so far.

I bought my PC at the beginning of 2021, the PC itself, cost me 2,115$. If you wanna include things like a desk, monitors, etc. It was expensive......
