As a wise man once said, "it's okay to like bad things." The Robotech RPG was a ludicrous kludge of a game. Remember, it was based on the Palladium Fantasy RPG, which itself was heavily based on AD&D 1st edition! The books looked awful, from the type of paper, through the horrendous typewriter font, and to the densely-packed two-column format. The art varied wildly, from great pieces (provided, no doubt, by Harmony Gold) to barely one step above child's scrawls. Books were late, almost randomly priced at times, and riddled with errors. On top of everything, those of us who knew of Palladium's shenanigans always felt a bit weird giving them money.
But...it was a glorious mess. And unlike other scifi franchises, like Star Wars and Trek, we never had to worry about some other company suddenly getting the license and us having to learn a whole new system. It was bad, but I liked it.
