I'm not playing much specific to it right now. I have a PC so everything gets played on that when I can.
I didn't see the point in waiting though. I would have gotten one eventually, might as well just get it on launch. It's already been out 2+ years and still hasn't had a price cut, so at most you're going to save what? $100? Maybe you get a slim if you wait long enough. Just don't care at that point. In fact I'd rather pay $500 for something that will get used for ~7 years as opposed to $400 for something I'll use for 3-4 years.
While I haven't played it that much since it launched, I have enjoyed Demon's Souls, Returnal, and probably a couple other things I'm forgetting. FFXVI comes out in two months, etc. On top of that you get much better versions of the PS4 games (and a much better experience at an OS level when I do play them), playing games on PS4 was absolutely painful even those last two years of it's cycle (hell, the whole time really, thing launched so underpowered).
