Yeah, I'm playing on PS4 Pro. I haven't noticed any problems. Whether it installed two versions of the game or not, I have no idea. I just waited for it to finish installing, per usual, then started the game. It didn't seem to take longer than normal, but I wasn't in any rush, either, so I'm not sure what the actual install time was. I just put it in rest mode and came back later, as I usually do.

I'm enjoying it. Only about two hours in, but I like the mix of exploration and combat. Although it's from Ubisoft, and I usually get bored of their games because of the bloat, things seem more "edited" here. At least so far.
The combat effects are a little over the top, but okay.
I hope the puzzles/challenges don't get too difficult later in the game. I don't want to have to be consulting Youtube for hints all the time. I can get impatient with that stuff. I did with Zelda, at times.
I like the humor. I appreciate anything lighthearted in tone, rather than the usual grim and heavy stuff we usually get.
