the mere act of explaining something to someone helps to clarify the issue in my mind
Also known as rubber duck debugging, or teddy bear debugging. It works very well.
I don't actually think PC gaming would necessarily be a huge adjustment to console gaming, incidentally - at least not in more recent years. The era of 'put the thing in the box and turn it on' is long since gone with the day 1 downloadable patches, such that buying from Steam is not really very different from buying from the online stores, and I believe Game Pass exists on PC (not sure, don't use it), and even PS games are making their way to PC now.
XBox controllers 'just work' on PC, it's possible to get PS controllers to work with a bit of fiddle. Heck, I've used Wiimotes with Wii emulators on a PC with no extra hardware (PC must have Bluetooth)
I will note that there is a pretty wide line between PC and mobile, if only because mobile games lean harder into the touch-first arena, though there are plenty of very successful mobile games that don't care (e.g. the average match-3 game works equally well between a finger or a mouse)
