in my opinion:
titles that are just awesome: Two Planets Approach the Roche Limit, The Star Conquering Traveler, The Raging Lion Roars, The World to Win, Faded Dream of a Psychomeddler, Settling a Score ~ Atone for One's Misdeeds!, Supreme Ruler's Coronation - OVERLORD, A Full-Speed Farewell from the New World, probably a whole bunch more but i'm gonna end there
titles that inherit their awesomeness from something else: The Wastes Where Life Began, "Mistilteinn, Tree Crown without a Ruler"
titles that are nice in some other way: From Those Who Departed for Space, I'm a Hungry Pink Puffball!, Soaring Determination: No Night is Eternal
titles that i pay more attention to than the song they come from: Please Don't Inhale the Cinema Patrons
a nice title for a not-so-pleasant song: Eternal Echo of the Thrilling Tour-our-our
unofficial titles that i prefer over the official ones: Moonstruck Blossom [official: Fatal Blooms in Moonlight], Looming Darkness [Another Dimension], Fly! Kirby of the Stars [Fly, Kirby!], Swole Dedede Scuffle [Macho of Dedede]
unofficial title where although the official one is cooler, i'm way more used to the unofficial one: Under My Control [Welcome Your New Overlord]
