Didn't find any on the website or any working links towards any of these. Wondering if anyone has made complete game rips for any of the games and if so, could they please upload them? Would appreciate it, thank you.

Jessie has a gamerip of God of War III if I'm not mistaken, you can find his thread here: Thread 57031

I think he takes requests, though I'm unfamiliar how he prefers to take them, I'm sure you could read his thread and see if he's willing to do the rips.
I'm not too familiar with the games myself, so I don't know how much music is missing off the Official releases. At first glance the soundtracks seem pretty sizable, and it looks like each game got it's own soundtrack. Was there something particular you were looking for unique to a gamerip?

Thanks for the response Mint! Wasn't looking for anything in particular, but I had read that there was a lot of missing music from the last release (God of War : Ascension) that wasn't included in the soundtrack. Perhaps I am mistaken, but thought I'd inquire because I really dig soundtracks, especially the ones Gerard K. Marino did. Think I also recall God of War 3 omitting some music from the official release.

Thanks for the heads up, I'll take a look at the thread.
