I asked myself, why nobody (from the anti-PS2-camp) gives Konami/Square/Namco some credit for their achievements on the PS2 platform?
Here are my assumptions, a bias is usually based on a reason. What could be the reason to compare the games of the PS2 to games on the DC/X-Box/GC in order to point out how badly the platform is? Even the design of the casing was criticised.
I guess everything started a long time ago, the Saturn was beaten by the PSOne, N64 was beaten by PSOne, DC was killed by PSOne/PS2. Still havin some great games on all beaten or killed platforms, Sony made it as market leader. Note: Sony was most the time the underdog visual-wise (PSOne VS N64, PSOne VS DC, PS2 VS GC/XBOX).
Realizing all this shows pretty clear: Nintendo/Sega fans having enough reason for some serious bias against the PS-brand. Now given the situation that Nintendo and MS released their platforms 18+ month later and gaining technical superiority, results into the situation at the moment: GC and X-Box(in fullforce/MS-enterprise-sponsored/Sega-powered) ... the AVENGERS ready to bring new hope to those who would love to see the PS brand fail. Pointing out weaknesses at every occasion, seems to be the only way to reinsure this hope. Superior sales of the PS2 are not helping to open those minds to the achievements games like WRC2, SH3, ZOE2, Burnout2, ViceCity or SlyCooper display.
This are just my 2 cents, I hope I am wrong and there is a better explication, otherwise it would be very sad.
