When I first got Plus for PS4, I automatically assumed that I had to download the whole game and keep it on the HDD when it said "download free", so I didn't bother with a few earlier on. When I found out once you add it to downloads that it automatically is added to your library I was a little ticked off. Why wouldn't they always have the "add to library" button regardless? Some of my friends thought the same thing until I eventually read about it and mentioned it to them.
As for SWBF2, I'm pretty sure that both options had no price but one wasn't selectable, and I believe there was an "add to library" button instead of "add to cart". After the version selection, it definitely didn't take me to any further purchasing screens.
I added both of these about a week ago, so maybe they changed something with the SWBF2 selection process perhaps?
So you had 2 options but only one was selectable? Now that's even weirder, because as you can clearly see, this was not the case for me. Incidentally, I did try this twice. Once when it initially went up, and again about 10 days later, so it wasn't some brief aberration. Anyway, glad to have another response from a North American/Canadian, because aside from you and Blood_Tears, all the other people who have responded both on VGC and PSN have all been from the EU, where this change apparently did not occur.
