A compressed ISO file is a smaller version of the original game file, which can be convenient for downloading and storage purposes. However, I must emphasize that downloading copyrighted content without owning the game or having permission from the copyright holder may be against the terms of service and potentially illegal.
A repackaged file, like the one you mentioned, is a compressed version of the game that has been re-released, often to fix issues or provide a more compact version.
God of War 2 is an action-adventure game developed by Santa Monica Studio and published by Sony Computer Entertainment. The game was initially released in 2007 for the PlayStation 2 console.
