Also, Nintendo has made efforts to target this audience even further by stating that two DS games, Brain Age to be released in April and Big Brain Academy in May, will be approximately $19.99 for the wide audience the game is intended to reach. There is yet to be word on how much games Nintendo's next-generation console, code-named Revolution, will cost to reach a similar intended audience.
Great news IMO, for the whole gaming scene, I only hope that this is the first of many (all), but I think this is only the logical progress if they want the big public.
