Believed to have been left by Extraterrestrials to hypnotize our kids while THEY take over our  planet - Four PlayStation 2 games. Included are SONIC RIDERS (E) and PUZZLEQUEST (E). Plus, SINGSTAR 90'S(T), and who could forget.... ummm... you know... Oh, that's right! HARVEY BIRDMAN (T). Gee, that alien stuff must work on adults too.
