Are there any games since then you think captured the feel of the unique discovery-based magic system?
A theme of a bunch of the comments is that the internet / audience makes this sort of thing impossible these days. One of my white whales for game design is figuring out if mystery, especially in multiplayer games, is still possible in a meaningful way.
You remove the “meta” from the game because every character has a different meta that is just a little too cumbersome to figure out in any way other than “feel” it.
