whoa. P vs P events? Definitely an upgrade from years ago lol
sort of. matches aren't like the history-mode matches, but are designed for this adventure only, and you cannot choose your rival, but the game gives you 3 choises (that you can randomly change) and you can select the one you want to face. at the end there's a ranking system that gives you nice rewards.
by the way I don't know how long does it last :
