Here's what I say.... Release it without sounds. I'm not kidding. Then, someone will make a sound mod for it with all the old sounds within the week. This will happen, undoubtably. Eveyone can just download that and there will be sounds, and there will be no-one to sue over copyright issues, as if the owner cares. If you ask me that's the best thing to do. Best, easiest, etc. Tell me what you think about that....
