The most interesting part of this for me is that streaming on PC is still supported which could become quite appealing to some as the 1st party lineup grows (for now it seems they are adding God of War, Spider-Man and Miles Morales. The first 2 have been on PC Now before, but only for 3 months each. Sounds like they're here to stay now).
This honestly is the perfect time for PS to expand their 1st party games into the PC market as the main downside that could hypothetically have had was lowering the demand for their consoles, but since they can't produce PS5s nearly fast enough to meet demand anyways, those extra software sales are pretty much just a win for them right now. Of course this here isn't a ton as long as it's only for streaming, so I'm hoping they also keep doing more ports. Quite frankly there might come a time where it's worthwhile for them to port every major 1st party game to PC, whether it's at launch or a year or so later, even with the extra time that requires.
