It's hard to overstate the sheer immensity of the PlayStation 2, particularly for those who weren't around during its heyday. Sony, the scrappy competitor to Nintendo, came out on top and dominated half a decade of gaming history by being a home to both AAA releases and beloved weird games, all under one umbrella. The PS2 may well have the best roster of video games ever assembled, which means there were a lot of influential games found on the console as well.
