Nemo is right in certian respects. If they aren't trying to ignore its base then they would have shipped many games that would pertain to its base. Many Nintendo fans like RPG's, are there any? Many Nintendo fans also like platformers, are they any orignal ones? Many Nintendo fans like Super freaking Smash Bros., is it here? These questions almost prove that Nintendo is ignoring their fans.
Nintendo needs to realize that it can do both at the same time, get new gamers while pleasing the old....I guess Nintendogs is a good example, but there are way better games that could do the same thing, but of course, better. RTS's and such can attract the market that console companies have always tried to get, PC gamers. What about RPG's like Super Mario RPG or Paper Mario, they definitely appeal to the masses (there easy to get a hang of and are easy to control, plus ALOT of fun). A pikmin game could be a perfect stragety game that could hit big with those "I need something to play other than DAMN SOLITAIRE." It could be easy enough to play since its would basically be "Hit button: Seperate groups, use touchscreen: highlight red group, use touch screen: point in direction to throw, hit button: throw, use d-pad: run away." Plus that again could pertain to the "I need to take care of something" group. A PDA accesory would be nice for the group that doesn't just want a game machine, or doesn't think it's worth to buy. What about the hardest group, the group that loves movies but don't care for games. They could make a game not unlike WarioWare, but instead play out scenes of familiar movies. For example, "Dodge Bullets" would showcase Neo as he dodged bullets, or "Order the hit" Could show you the scene that we always wanted to see in Godfather movie, where he basically orders the assassination of everyone in the movie. Extra goodies, such as never before scenes would attract alot of people (they love that stuff). Of course it would be a pain in the arse to do that (licencing fees and such) but that's why they're the hardest groups.
