Kinda sucks for me, as I’ve almost exclusively used gift cards for the last few years. I get a bonus tax-free credit card by my employer, which I can only use at retail stores. So those were a great way for me to use that card to buy games. It was also a good option for people who wanted to avoid payment providers like Visa/Mastercard etc. Oh well.
The last time I was given a steam gift card obtained at a brick-and-mortar Gamestop, it was a hash of numbers printed on a receipt I had to (painfully) type into Steam manually.
It didn’t even come on a pretty card, and that was about ten years ago.
