New Million-Sellers! Kid Icarus: Uprising, Pokémon Rumble Blast
Talk about a close shave. Two 3DS games sold their millionth copy in the final week of 2012.
Kid Icarus: Uprising reached one million sales in 41 weeks. There isn't much to compare its sales to, since the series hadn't seen the light of day since the early 90s. Nonetheless, the original Kid Icarus for NES sold 1.76 million units in its lifetime. Sales data for Kid Icarus: Of Myths and Monsters for GameBoy are unavailable.
Pokémon Rumble Blast, on the other hand, took 72 weeks to reach one million sales. The previous (and only other) game in the spinoff series was a WiiWare title; as such, sales data is unavailable for comparison. Rumble Blast has taken longer to reach one million sales than other, more well-established Pokémon spinoff titles, such as the three DS Ranger games (the slowest-selling of which reached 1 million in its 53rd week) and the three DS Mystery Dungeon games (the slowest-selling of which reached 1 million in its 54th week).
Both games seem to be slowing down, and are unlikely to reach 2 million sales. Judging by previously mentioned comparisons to other Pokémon spinoff games, Rumble Blast seems set to retire at about 1.2 million lifetime sales. Lifetime sales of Kid Icarus: Uprising are still... up in the air. It seems to have received a boost during the Holidays, selling over 100k units since (and including) Black Friday week, about one-tenth its total sales. The game should outsell its companion (Pokémon), at the very least, for 1.3 million or higher lifetime sales.
