I picked up my copy of Other M over my lunch break, and so far I have to give props to Nintendo on one thing: that Art Folio is surprisingly (and pleasantly) classy. It's a big pet peeve of mine when companies (particularly anime companies) pack in postcards or whatnot with their DVDs, but they give you nowhere to put them so I end up having to chuck them into a bin I have set aside for that very purpose. The postcard artwork for the Other M folio, however, comes in a black envelope made out of what looks like high-quality cardboard (which has an almost felt-like texture to it). The artwork inside is quite lovely; on high-quality paper; and surprisingly large, with captions on the back of the cards. I'm usually very unimpressed by Nintendo pre-order bonuses, but this one's very satisfying. My only complaint is that because the fold for the envelope is on the inside, it can be a little hard to get the cards back in it.
Also, I wasn't terribly fond of the Other M cover art when I saw it online, but in person it looks pretty nice. You can't fault Nintendo for the artwork in this game, that's for sure.
