The bromance between Jaune and Adam is honestly the best part of the story. The ovearching plot is a nice attempt at explaining the world of RWBY, but there really are too many fights without enough to differentiate them, or a real sense of drama. I'll read it again, but not for a while.
Jaune Arc gets the ability to live life as a game. As expected, massive power growth ensues. As is slightly less expected, curbstomping absolutely everything is not possible. The threats scale with his abilities, and nothing seemed overly contrived. Completely ignores (IIRC) everything after season 1 or so. Also apparently the second fic that Ryuugi has ever finished, so, yay?
