8 Things We Learned From The New Pokémon Sun/Moon Trailer
4. The Four Player Battle Mechanic
The trailer didn't tell us much more than we already knew about the four-player arena feature, but it did make it apparent that it'll probably be bloody annoying, with opposition Pokémon capable of harming all three competitors in a single stroke.
Will the four-way battles have any place in the game beyond the multiplayer? The trailer revealed absolutely nothing to this effect, but that won't stop me wildly speculating. The mechanic is in place, so why not? Anything that freshens up the increasingly tired experience is a definite plus in my book.
