Can't believe the PULSE slipped my mind! Mega evolving before it was cool. And brings me to another thing that I love! The Pokemon. They take such an active role in the games. I mean, the main games do simple stuff like "ooh that Pokemon is carrying a box". But in this game the world actually feels teeming with life. So many Pokemon just roam around, are part of events, and used in clever ways in puzzles.
And the PULSEs are the epitome of this. Actually using a Pokemon (other than a legend) to cause some mayhem and show off their true power. A side we hardly see in the main games. Most things they do in the main game is block roads lol.
But yeah, this really is one of the key things I love about this game.
