soooooooooooo..... sad to say that ps2 is a sixth generation console and xBox360 is a seventh generation console. So, there will be no comparison at all between these two consoles. I want to tell one thing, ps2 9000 series rates up to 8K, where the xbox360 core system or arcade version is near to 13K. Only 4k difference between a generation. What a mess up..

!
@ mandar....
dude,
there are four versions of xBox 360
arcade (around 13k)
core system (discontinued.., but you can find it in many stores. 13k)
premium(20k)
elite(35k i think.)
ps3
20gb (20 - 22k)
40gb (24 - 26)
80gb(28- 30)
in ps2, you can't play pirated games because, there are no mod chips and no one who can pirate a game in blue ray.
you can mod and play the pirated games in xBox360. But it is illegal. And if you get affected by rrod, microsoft will not replace your console.
