Back when Robotech was airing in Atlantic Canada in '85-'86, I was hooked on that soon enough, not knowing its history as the three different anime series. I found out when I bought the Robotech RPG, and there were appendix notes on the "Supervision" and "Inspection" armies of the Protoculture, how Kamjin scavenged three Glaug pods from a forgotten weapons depot, and lots of mecha notations. "Wow," I thought, "there's a whole story that's been hidden here. I must know more. More!"
Then I found the Macross Compendium online, catalogs of anime model kits, a 3rd-gen VHS Hong Kong-dubbed DYRL movie, and so on. The Robotech Art 1 book explained how Carl Macek hammered/mutilated the three different series into something with 65 episodes for TV syndication. I loved finding out about it all.
