I'm running out of rain so I guess I'll keep this parade dry.
Anyway, as for the games I'd like to see on the next Nintendo Handheld.
I want to see a reclassification as to what makes a handheld game suitable on the system. Currently way too many people feel that handheld games are just console games with older tech. This then morphed into 3D for home consoles and 2D for portables. This is all just silly. We should be focusing on game design in this day and age... not technology.
Portable games should be games that require shorter play sessions first and foremost. They can still be epic games, but you should always be able to sit down and play in 10-20 minute spurts.
They should also take advantage of the fact that they are played in a variety of locations. Accelerometers and GPS would allow for amazing new games. Make a Pokemon game where wild pokemon are only available in certain areas of the world during certain seasons. I really liked Jonny's ideas on RFN. Take the pokewalker idea, build the tech in, and expand on that.
Nintendo needs to differentiate the handheld scene, not just from its competitors, but also from the Wii. Otherwise it will remain a redundant piece of hardware for many of the blue ocean buyers. Why buy a Wii if I have a 3DS? Why buy a 3DS if I have a Wii?
That's why, to me, 3D seems to be nothing but a gimmick to superficially differentiate it from the DS. I hope that proves to not be the case and it ends up just being one feature of many improvements. I know, that sounds seriously similar to many people's view of the Wii. I didn't share that view though, and, in a way, I was burned. Motion controls were really the ONLY significant hardware addition to the platform and I think they will prove to be a much more significant innovation than a silly 3D screen will be.
There, I guess I still found some rain.
