This is exactly why I mention Baldurs Gate, because dozens of smart people took thousands of hours to reverse engineer what would have taken the legal team hours and one coder 15 minutes to relicense and release publicly. Also, the Infinity Engine was used in half a dozen titles, and while it is detrimental that pretty much nobody releases game assets under permissive terms, my point is that games are lost to obscurity because their engines don't work. For better or worse, the game data is just as compatible with its engine as it ever was.
