I'm finishing my basement and some of it will be a home theater with a ton of consoles.  I have a PS2 in my vertical cab for some cool shmups and love it.  I hooked up a second one to my TV via component but the only horizontal game I have right now is Metal Gear solid 2.  While the PS2 looks great via component, I have a PS3 as well and really like the cleaned up ports on my HD TV.  What PS2 games that haven't been ported to PS3 are worth taking a look at?  If there are any that the PS2 versions is somehow superior to the to PS3 port, I'm happy to take a look at them too.
