I know what you're thinking, "Paul, did you just say "detective Pikachu and not make a joke?" Yes. I did say Detective Pikachu and no, I was not making a joke. But it looks like all the beautiful Japanese folk (and those who can speak/read Japanese) will be able to play Meitantei Pikachu: Shin Konbi Tanjyou, or if you want the English title, Great Detective Pikachu: The Birth of a New Duo.
I'm not going to lie to you guys. I don't know what's going on in the debut trailer. All I know is that I can see Pikachu wearing a really cool detective cap, getting a kiss from a shadow-human, and at one point I even see Pikachu drink coffee. Those are all of the necessary requirements to be a detective (and I know this because I tried out for detective school but I couldn't get a shadow-human to give me a kiss so I flunked out).
I don't know when this game will hit Western shores or if it'll even get localized (because I don't do research, I just like looking at pretty things) but if you're in Japan or understand how to get access to the Japanese eShop on your 3DS, then you'll be able to play Detective Pikachu: Super Awesome Game Paul is Intrigued By (not the real title) on February 3rd, 2016.
[Note: Although I don't understand Japanese, I love the rough voice that comes out of his mouth. So majestic. Much detective.]
