Legacy of Time was Journeyman Project 3.
Journeyman Project 2 was called Buried in Time.
Pegasus Prime was a remake of the first Journeyman Project game. Originally it was only made for Mac, but they remade it for PC many years later (like 17 years later, almost unheard of).
The original Journeyman Project game was from 1993 and is quite pixellated. I'd recommend Pegasus Prime instead. If you liked Legacy of Time, you'll probably like Pegasus Prime too.
Journeyman Project 2: Buried in Time was a good game, but the viewing window was smaller than in Pegasus Prime or Legacy of Time, as you can see in Mobygames pictures
