I've been wanting to get rips of the dialogue from the Ace Combat games for a fan trailer for it's 20th anniversary. Any idea how I can get a hold of them? (or any game in particular?)

(If you guys don't allow such rips, let me know please.)

You can find tools to rip the dialogue audio pretty easily when it comes to older games. Not so for new ones though. If all else fails, check to see if Ace Combat has audio options. Disable everything except dialogue and record the audio yourself ;)
