"well I've seen the front cover and my super KAWAII psychic powers say it is the bestest game ever!
I know i'm psychic because I guessed the same thing about HHD! xD"
at worst I just expect it to be rather underwhelming and all but completely forgotten about after a few months, which is certainly not the same as being an actually bad game
I mean, for some people it's really easy to tell if you're going to like this or not. You know what it is. You either like party games or you don't. So, at the very least people can say whether they will like it or not already. Even though the game is not out.
Now, as far as judging whether the game is objectively bad, no. Nobody knows that yet.
