I've seen some snippets of these materials over the years. My question is are these materials available in full? I'm not asking for pirated copies, just wondering if these sources have been fully mined for information. I know supplementary Japanese materials for Sonic Adventure and Sonic Adventure 2 were featured in strategy guides and perhaps there is additional (clarifying) story content to be found in these books as well. Just curious if this is a route that has been fully-investigated or not. Thanks.
