Going to have to nitpick this. My love for OG XBOX and where it got its foot in the door in the west is because PS2 didn't really do shooters that well at all, whereas XBOX not only had Halo but pretty decent and faithful PC ports, like Wolfenstein when PS2 only got butchered version. Looking back I think PS2 is great but at the time when I was in a heavy shooter mode PS2 was a dust collector.
That's why last gen MS had all the deals and rights for things like COD because the perception at the time and for quite a lot of even the PS3's lifespan even though it did them fine was that PlayStation sucked for FPS.
Despite the superiority of the Xbox and the Windows version for a lot of games, all you'd hear about was the PS2 version:
COD, Max Payne, GTA, FIFA, Pro Evolution, Medal of Honour, Hitman, Bully, Manhunt etc
Granted, the PS2 had some unique exclusive shooters like Killzone, Cold Winter, Black etc that used the hardware to the limits. Games like Ghost Hunter had also nice graphics.
Though this trend was justified since stability and gamepad support were not at their best on computers. Xbox was not as popular
PS2 not only dominated the industry. It also made dual shock controllers more popular than ever.
Well actually... Ps2 emulation brought about ways of doing things on actual ps2 hardware like obtaining true 16:9 along with progressive scan for games that did not support it. You had to sometimes patch the ISO's or use a boot disk, or even a combination of the two, but the ps2 was entirely capable of progressive scan for a lot of games. You can also just run the emulator on a good pc and up the internal resolution. A lot of early games were field rendered though.
I remember in the early days of PCSX2 when emulator could run mostly Japanese games since they were easier to emulate, the forums and the developers were branded as anime weeaboos
This disappeared later when western games began to get emulated too.
