Well, theres the basics:
You get the system, 40g of course.
An rca cable and power outlet, no hdmi or ethernet cords.
One wireless controller with its usb cord.
The console itself has two ports, but still you can have 4 controllers on it wirelessly at once.
Possibly Spiderman 3 the blu-ray movie, not the game.
No free games, sorry, not lately anyway.
The 40g are not backwards compatible though, remember that, so no ps2 games for you.
And it is wifi compatible. Check it up.
