The way you just described it Hakuro, is almost exactly the same way the Lore information worked in Star Ocean: Till the End of Time, as you progressed through the story and sidequests you slowly unlocked more history of the universe you were playing in and even the 4th dimension which was also a part of the game, or rather, the "game" since the it was a virtual world that was fully active long enough it somehow formed Artificial Intelligence of its own and also became more "real" like the real world. Crazy game, but it was a lot of fun and the lore section filled up a lot by the time you cleared the story and sidequests and even the extra dungeon after clearing the story itself.
