For those of you who've never heard of Boku no Natsuyasumi (aka My Summer Vacation): it's a Japanese PlayStation game that was developed by Millennium Kitchen and published by Sony Computer Entertainment in June of 2000.
True to its name, the first Boku no Natsuyasumi (there have been four--one each for the original PlayStation, the PS2, the PS3 and the PSP) stars a 9-year-old boy named Boku ("I" or "me" in Japanese) who spends his summer vacation with relatives in the Japanese countryside.
For the most part, players are left to determine how Boku spends that vacation, which spans the 31 days of August 1975. Among the options: exploring the wooded surroundings, catching bugs, collecting bottle caps and flying kites.
As for the blog posts that are chiefly responsible for me picking up this import-only gem (or so I've been told): this recent post ("Summer's Here!") on the Shinju Forest blog, this post ("Childhood on a Disc") from Unwinnable.com and this post (from 2011) on Kimimi's Blog.
I haven't yet received the copy I bought, by the way, so I can't share any thoughts about it. As soon as it arrives, and as soon as I give it a bit of attention, though, I'll let you know if it lives up to the hype built by the aforementioned bloggers.
