Fact is 90% of the console market now is the Western gamer. A large chunk of Nintendo's handheld losses are coming in the West too.
Nintendo can't fix this just by throwing Mario, Pikachu, etc. continually at the problem. They need something that can be relevant to Western consumers and they need it fast.
My advice to them would be to cut a deal with Disney/Marvel. There aren't good games for a lot of their big IP like Guardians of the Galaxy, Avengers, Spider-Man/X-Men, etc.
Not only are there not good games for these hugely popular IP, they are the golden demographic ticket for Nintendo -- they appeal to kids AND teenagers AND even adults pretty much equally across the board. If the quality of the games was high they would sell, no doubt.
Anyone else have any suggestions?
