I have pretty much the complete collection of Legend Entertainment games, not that there were a lot of them -- even with all versions that's barely two shelves. Really good games, hard to find these days. I believe, Atari has the rights to their games but there is a problem of licenses -- more than half of LE games were based on books. Timequest, Spellcasting trilogy, Eric, Superhero League of Hoboken, and Mission Critical don't have that issue. Would be really great to see these and, if possible, the rest available here.
As a trivia, there are a few Legend Entertainment games on GOG already: Star Control 3, Unreal: Return to Na-Pali (part of Gold), and Unreal 2. No adventures yet (unless you count SC3 as an adventure).
