I've heard nothing but good things when it comes to this port. I just watched the whole video, and it seems like it sits comfortably between last gen and current gen. Better resolution and a more stable frame rate make this port a winner, imo! That $60 price tag is really holding me back from picking it up, though.
Just an FYI, this game includes the Reaper of Souls expansion which retailed for $40 when it launched, which was probably the main thing that 'saved' Diablo 3 and made it a viable and fun game. They took a very different direction at first. The Switch version also contains the Necromancer DLC, which otherwise costs $15.
I can understand the higher pricepoint when it's both a proper port and contains all the extra content.
Diablo can be pretty fun. Especially when playing with friends.
