sounds like a regular ps2, a controller with extras not normally found on a regular controller (such as turbo, slow-mode) and possibly a DVD remote (looks like a TV remote, with the playstation buttons).

the controller extension works like any regular extension cord - like if you're vacuuming really far away. obviously, this extension is for ps2 controllers.

when they go into all those details, they put every little thing you can do, to make it look like a lot more than it actually is.

S-video cables are for newer tvs that allow you to hook up through the S-Video input rather than regular auxillary (red and yellow cables)

like the other guy said - it's just a lot of junk, and should not raise the price of the ps2 that much. (perhaps adding an extra 1/6 of the price) (i do that in fractions, as i don't know what currency you use, sorry)

if someone is trying to push you into buying that, perhaps it is extra understock. i advise you to see how much it is for just the ps2, and how much for 1 extra, standard controller (which can be bought elsewhere), because the rest of the stuff is useless
