I'm gonna take a wild guess and assume the previous Legacy Collection threads are long gone.
One thing i've seen people complaining about is how only the first collection in on the physical game card, and you have to download the second collection, similar to what was just done with Bayonetta. However, if you're like me and are just gonna download both digitally, anyway, then it's really just a non-issue. It does look like the physical version comes bundled with some physical swag, but it just looks like a cleaning cloth, and while i can't speak for others, i really don't give a crap about something like that. Now if it came with another exclusive amiibo like LC1 on 3DS did, that'd be a different story.
