I played the Fatal Frame demo and didn't find it as scary as it could have been. Your first encounter with a ghost holds your hand with tutorials so much they stop being scary from the get go. The right stick camera doesn't act as you think it would and the movement of the character made me feel uncomfortable, not in a spooky way, more of a motion sickness lack of precision kind of way. I did like some bits though, the notes you find are quite interesting and not generic blah blah they're coming blah blah biochemical weapons of resident evil. Or the technobabble of Metroid Prime. Some scenes were quite effective like the one of the cliff face and the sunset, and the one where the dude sees a vision of a boy commuting ritual murdur then waking up not knowing if it was a dream or a memory, wtf that's messed up.
SMT 4 has miiverse in Europe, it's also literally the only difference between the EU and US versions despite being released more than a year after, only on the eshop.
Kacho On! NCL's YouTube is super weird, there's some series about a papercraft puppet thing on a wooden stick kind of deal, that goes to a store, buys a Wii U, gets abducted by aliens and is forced to play Wii U with them. Presumably antics ensue as well as informative gaming tutorials, hints and tips.
