Legend was, simply put, the most consistently good adventure game company. LucasArts, Sierra, Infocom, they all had their duds. Not Legend. Since this thread has been revived, I'd like to mention that I've been working on an exhaustive article that will cover the history of Legend in addition to reviews for all their games
By far their most overlooked title is
Mission Critical, which is in my opinion the best sci-fi adventure ever made.
