Essentially the best giant-monster-based fighter of them all. It really captures what you want from a game with that premise. You can play as a nice variety of kaiju/monster archetypes, a godzilla, a mecha, giant ants from outer space type thing, an atomic robot, a big giant-ray harryhausen statue guy.

And gameplay wise it allows for climbing up giant skyscrapers, throwing buildings and vehicles around.

All matched up with a great atmosphere and visuals, it's aged very well.
