Lots of characters, each with their own gameplay; a good amount of content (and by that I mean not "too much", like in FE warriors, or the first hyrule warriors), organized in a different way cause there now only one mode / campaign.
I like that they used the same engine, or at least the same artstyle, as botw + that they made this a prequel.
Or should I say they sold this as a cannon prequel, but in the end heroes from the future come save the past (for no reason cause botw is still a thing ?). That's kind of a bummer, tho I understand why they choosed that ...
