The PS2 software is now dominated in the second hand software market. Most of the older games are actually better than the new ones. Final Fantasy X for $10 or The Simpsons game for $40?
The PSP and PS3 are falling victim to Sony's marketing of them being used as multimedia devices rather than a gamming platform. Ex. Many PSP users are using it simply as a MP3, WMV player and many PS3 users are just using it to surf the web and watch movies on.
The 360 emphasizes online gamming and Live the most so games with Xbox Live features sell fantastic.
The Wii only plays games for the most part, no games ;no function
