I really, really hope this thread is a joke. I mean,really. Sure, you can argue that the quality and frequency of Nintendo's releases has gone down since they started riding the Wii gravy train to loadsa money-ville, fair enough. But how much of a petty, self-obssessed sense of entitlement do you have too have to start bandying about the world "betrayal"? When your best friend shags your girlfriend and runs off with her after drowning your puppy in the bath, that would be a betrayal. If your brother souls his soul to a demon for infernal powers, kills all the rest of your family and chucks you off a cliff while cackling Vincent Van Price style, yes, the word would be very appropriate. But when the greatest crime here is to be wildly successful making games you personally don't enjoy, that's not a betrayl so much as a sound bussiness strategy.
I mean,really folks, where did our deep seated, misty eyed loyalty get Nintendo in the end? Thrid place.Rotting away from the console market like a gangrenous limb while Sony made tons of cash appealing to Johnny FMV gawp with massive amounts of cinematics and gore then using that to nab the most quality titles. I'll admit that despite playing through No More Heroes at the moment, I don't get a massive amount of use out of my Wii, but its great for playing Wii Sports or something when my Nephew comes down. It has a function that it does well. If I want a meatier game, I'll load up CivIV on my lappy for the umptieth time or shell out for flashy shooter 1000.
Find some games you enjoy and give Nintendo a formal doff of the cap for their sensibility without a temper tantrum. And let's face it, the you that first fell in love with nintendo probably has a lot more in common with the archetypal 8 year old kid currently playing wii sports or Galaxy than the you of now. This too shall pass matey, no use whining about it.
