Great post Grampy!! I agree with pretty much everything. I DO agree with point #1. I think the majority of Wii owners (excluding the Nintendo fanboys) just don't play regularly enough to follow a story. I know I don't.
However, a story is fine as long as it doesn't interfer with gameplay. IE: I have Lara Croft Anniversary and I no longer remember why I'm doing the quests but that doesn't interfer with my gameplay in any way. Same with Mario Galaxy and even Fire Emblem, the story is there but is not of concern gameplay wise.
Here I'll add a point:
12: Keep the controls intuitive. Most Wii owners are irregular players. Therefore having complex controls that need to be memorized and/or mastered will kill sales. - See sales of Shaun White Vs Skate. Keep the controls simple... but deep. Brawl is a great example of this.
13: Get some women game designers working for you. Wii (and DS) have a HUGE female audience that are dying for games to play. But don't make 'girl' games - like a blockbuster action movie throws in some romance your games should have elements that appeal to women too (as well as guys). Also, think outside the traditional box. SIMS is still one of the biggest franchises in the world because it appeals to (mostly) women. While SIMS itself may not be the answer on a console a non-traditional games that appeals to a woman's sensibilites instead of a teenaged boy's (without being 'girlie') could sell millions. Animal Crossing and Nintendogs are good examples here.
