Ah, Twitch Plays Pokemon. Rock on, you crazy thing.
Nia's English voice overs are stilted and lacking. Thankfully, you can turn them off or switch to the Japanese voice overs. Can't quite pin down the Japanese voice actress by ear. I'm mulling over Marina Inoue (Alicia from Valkyria Chronicles) and Megumi Toyoguchi (Winry from Full Metal Alchemist). Leaning towards Marina; probably someone I didn't know.
First hour impression: this is pretty fun and the right amount of complexity for my head. Messing around with Pikachu Libre is such a joy. I'm trying to find as many opportunities to use the Duel Phase, Counter, Down+A move Wild Charge (AKA the Stone Cold Stunner). I pat myself on the back when I remembered that opponents who have crashed against the wall are still vulnerable to attacks and executed a Wild Charge.
Oh, in case anyone was wondering, the amiibo support is of the uninspired Hyrule Warriors variety. You get five slots pull each day to earn an avatar item or in-game currency.
