Japanator: "The World of Golden Eggs, that anime series we all laughed at four years ago is by and far the best-selling anime of the last decade. Selling over 170,000 discs, the series blew out Gundam Seed Destiny (#2 at 79,000 sales) and Bakemonogatari (#3 at 76,000 sales) by a long shot.
The rest of the top ten is rounded out by Gundam SEED, Full Metal Alchemist, Code Geass, Macross Frontier, K-ON!, Code Geass R2 and The Melancholy of Suzumiya Haruhi -- all titles that we shouldn't be surprised by. Most of these titles are driven by two things: moe/hardcore otaku, and Boy's Love/shonen. The latter category explains why Gundam Seed Destiny ranks so high -- it has an unbelievable female following, just on the basis of pairings alone."
