Metal Gear Solid (Playstation, 1998)

Get ready, because 1998's game is one of the most iconic of all time. A year earlier, Final Fantasy VII steered the N64/Playstation war toward a Sony win. That game single-handedly drew the massive RPG fanbase - which Nintendo at one time had a lock on - away from the N64. Sony managed to keep them there by, you know, having RPGs (something the N64, for the most part, did not). Nintendo fired back with the awesome Ocarina of Time, but Sony was ready and countered its holiday release with Metal Gear Solid. Nintendo had finally met its match, it seemed.
