Sublime from top to bottom and stands alongside Resident Evil 4 as among the most content, feature, and conceptually dense titles of that generation. Like the aforementioned, every room, encounter, scenario, and idea appears meticulously hand crafted and unique alongside all the others, the experience as a whole made up of distinctly individual parts stitched together. You can effortlessly rattle off a hundred or more unique sequences and events from start to finish. And importantly, it manages to keep the Metal Gear formula fresh and interesting without relying too much on directly replicating the design of Metal Gear Solid 2 (which was a clear evolution of Metal Gear Solid), but never strays from staying distinctly Metal Gear in vision.
Purely in mechanical and design evolution, the jump from Metal Gear Solid to Metal Gear Solid 2 is probably more significant and impressive, but as an overall experience and vision Metal Gear Solid 3 impresses me far more.
