Still Playing...
Growing up with the series, Metal Gear Solid was the first gaming franchise that not only immersed you in story, but make it essential. The voices, the characters, the lines we all iconic. (Horrible impressions of Snake still circulate amongst my friends... "Master MILLER!") And here we are, over a decade later, and Snake (Hayter) still leads the front as one of the most engaging and complexly simple characters in modern myth.
I would write more about the graphics, the gameplay and the style but others have said it better than I. Peacewalker will go down as a the definitive game for the PSP and will be cherished in anthologies to come.
Buy it... go on. Seriously...
