In fact, i like what Nintendo CREATE, not Nintendo itself. I would say that there's some Nintendo philosophy i like:
To me, making a videogame is just like music, movies or painting or whatever - a form of expression. Yes, it's an art. Those form of expressions are good when motivated by true will, creation will. Those form of expressions are bad when only motivated by money. Only for money they lack spirit, you can't dig a deeper message anymore, you can't feel the love. Nintendo is (was?) a develloper who actually made games with alot of spirit.
I feel that especially Miyamoto was develloping games like "HE would like to play it" and not "like everyone would like to". This is what i like. This is what makes gaming evolve, this is what drives creation. Today's focus group games don't have much spirit and are only good at raising money, they don't have that "something more" that a CREATION have.
Now some games i want to point out (you'll notice that i prefer older Nintendo stuff though, Mario Sunshine / Wind Wanker / Prime2 and the lastest franchises like Animal Crossing are leaving a bad taste in my mouth)
Super Mario Bros, Zelda, Metroid, Super Mario Bros 3, NES Open,
Super Mario World, F-Zero, Mario Paint, Sim City (ok, not really Nintendo's), Super Mario Karts, Zelda ALTTP, Star Fox, Super Metroid, Earthbound, Yoshi's Island,
Super Mario 64, Starfox 64, Zelda OOT, Zelda Majora's Mask, Paper Mario,
Metroid Prime, Mario Golf Toadstool Tour, Pikmin 2,
Those are Nintendo games i really liked and i hope they will continue to give us good gaming like this.
