Until I watched all of these videos, I didn't understand people's disappointment except for the "you can run into other players". I guess I get it.
As someone who enjoys this game and have a good chunk of hours in it, this type of either lying or BS behavior should be treated as false advertisement because it's exactly just that. I can see maybe a couple of things not happening and there should be a few strikes before it's critical, but after watching some footage today and see all the crap they said you could do and you can't, I just don't get why anyone is trying to silence others for speaking out about it. If you say there's some form of MP (like Journey MP), if you say you can land on an asteroid, if you say you can do X, Y, and Z and all of that is a lie, then you've falsely advertised your game.
This is coming from someone who still really likes what I'm playing. I just don't ever read up on games because of games from the captain of false advertising, Peter Molyneux. It's best to just watch a few trailers, read a bit about what people have played and anytime you see assumptions in an article of what the journalist said you could do, take that with a grain of salt. Then throw that salt in a barrel of salt and try to find those salt crystals again.
Persona 5, I'm just going to trust you're going to be a new Persona game equal or better than Persona 4 with a new story. That way I'll never be disappointed!
