bottom. At a Nintendo Conference on October 2, 2008, Nintendo's president Satoru Iwata announced during his keynote address that both games in the Brain Age series were redeveloped as two DSiWare games called Small Brain DSi Training Everyday for Adults Literature Edition and Science Edition. The DSiWare iterations include training modes from the previous two Nintendo DS games, including new ones that take advantage of the Nintendo DSi's camera. Brain Age 2 was given generally favorable reviews, receiving aggregated scores of 77% from Metacritic and 79.04% from GameRankings. Praise focused on improvements made on Brain Age, while criticism targeted the game's inability to consistently understand written and spoken answers. The game was voted IGN's Reader's Game of the Month for August 2007. Remarking that Brain Age 2 uses the same formula as Brain Age "with some different variables thrown in", Game Informer noted that players' opinions of the original Brain Age will most likely be similar to how much they appreciate Brain Age 2. GameZone was excited about the Sudoku portion of the game, which they complimented was "worth the entire game itself and will provide many hours of fun". They found the daily training and quick play modes "simply addictive", and appreciated the game's "simple and easy to use interface". The video game website IGN felt differently, however, noting that the challenges felt fresh, with the exception of Sudoku. IGN agreed with GameZone on a particular point, however, writing that both the original Brain Age, and Brain Age 2, have "calm, clean interface[s]". The television series X-Play was intrigued by Brain Age 2s promise to improve a person's intelligence. GameSpy called the game "the ideal video game gateway drug" because of its accessibility to a wide variety of people, lack of requirements for special physical dexterity or experience, and regular reward system to motivate the player. They also considered Brain Age 2 a "noble effort towards the betterment of our mental health through a painless training regimen". Game Revolution complimented the game's intelligent use of Nintendo DS features, "fun" sound effects, and "competent" handwriting recognition. Singapore's The Straits Times considered Brain Age 2 a good investment, despite noting that hardcore gamers might find the minigames "gimmicky". Recognizing that Nintendo intends to use the game to target baby boomers, The Globe and Mail writes that they were tempted to play the game at work and justify it as a self-improvement
