I have added Metal Gear Solid 2: Substance to my collection. The rereleases of games are, by far the way to go. All of the extras packed into the MGS special editions make them the obvious choice.
Perhaps I will wait for my MGS 4 limited edition PS3 before I buy. Heck, if I didn't already own a PS2, I'd buy the Final Fantasy XII box set slated for release in Japan!
Truly new editions of old systems or games are the way to go. Early adopters suffer so much for good products.
