Are PS2 games compatible with PS3 console?

There are no longer any PS3's being produced that will play PS2 games. The 80 gigs used to, and now they don't. I think the last ones that did were the Metal Gear solid limited editions. The 60 gig PS3's also had backward compatibility. However, it was encoded with hardware as opposed to the software that the 80 gig uses and therefore had different problems with different games, as does the 80. The 60 is generally thought of as more compatible with older games than the 80. You can find lists of games that wont work with either system, but they are few and far between. As of right now, you cannot buy a new PS3 of any size that has the ability to play PS2 games unless you buy a used one.
