Hasn't Steam just beat its record of simultaneously online users? And while I'm sure Steam Decks contributed to this, we're taking of numbers an order of magnitude bigger. Hell, PC gaming is doing so well that we're seeing until then console exclusive games come out on Steam.
I think the problem is that it's super popular for those who already own a PC and have a huge Steam Library. I got console friends wanting a Steam Deck but ultimately don't want to buy one because it means rebuying their games.
