In total figures the PS2 easily.
In percentaged relation to its own good games the Wii would win this contest by far.
Just my experience after updating multiple ten thousands of games.
Fun fact: both Systems are the ones I own the most games for.
I guess I can't live without my weekly dose of crappy games.
