Reincarnation of Isabel is correct. The last film is an Italian poster for a Godzilla title. The image of course has nothing to do with the film which makes it difficult to identify.
Well, it's what the Italians call Godzilla. I knew it was the Italian poster for a Godzilla film. I just lazily wrote Gorgo. My mistake, thinking you wanted the Italian title. My fault. And to be fair, Zbinks got it right first. He deserves the credit. The Italian title of the poster you posted is Il Ritorno Di Gorgo translated "The Return of Gorgo(Godzilla)" Italians changed the original title ....... Which is Son of Godzilla.
According to IMDB this is actually the Italian title for Godzilla's Revenge and not Son of Godzilla. Here is the example of the entire Locandina as well as the Locandina for Son of Godzilla.
Well you picked a big controversial poster for your game. The both posters are Son of Godzilla. The Italians gave the credit to the wrong director on one of their posters. They reissued it. See this DVD cover: Now look at the back: The back of the film. That's Son of Godzilla still shots. Not Godzilla's Revenge akaAll Monsters Attack (1969). Which is the little boy who has a dream, etc.... Son of Godzilla was directed by Jun Fukudo. Not Honda ... as labeled in the poster or back of DVD. The Italians have used the ship poster for Son of Godzilla. Why? Ask them.
Germany regularly calls kaiju Frankenstein monsters and I think they call Megalon King Kong too. So they're all over the map.
