A few months ago, I bought a Famitsu magazine from Nippon.
It came with so many goodies inside, including: A Lost Planet booklet guide, a DOAX2 calendar, an Idolmaster poster (with Makoto, my beloved tomboy), and a couple of Xbox 360 skins (I put the Onechanbara one on mine).
It was quite fun going through the hearty contents of the issue, specially considering these cost 350 yens or $3 in Japan.
Did you ever buy magazines with goodies growing up? I had a few, which usually came with demo discs, posters and stickers. I still have a Metal Slug poster, which came with one of them.
One I wish I had, is the PSM stickers for PS1. I love putting old videogame/anime stickers on my consoles, and these have great artwork.
