Really the main one is Server 72 ([LT] Server 72 [COMPLETE]), because the blind experience is absolutely key for it. A lot of awesome chapters to figure out with a huge array of tools, I could go back to it and try to solve it with different tactics, but knowing ways that work will always be in the back of my mind.
Then there’s The Dark Amulet ([FE8] [Complete] The Dark Amulet v1.6 (08/08/2024)) which is a very rare case of a hack where I’d be happy to experience the story a second time blind.
