This is the box set Simitar released in 1998 which contains the five Godzilla films they released on DVD. Like the DVDs themselves, they were released in order to cash in on the American Godzilla film, GODZILLA (1998), that was being released that same year. The set really doesn't contain anything new over buying the discs separately, except for the box they come cased in. The purpose of this set, like most box sets, is that it costs less versus buying the discs separately.
