I think yes because the people that bought Wii has moved to smartphones, tablets and social games (that's why no one buys Wii U now)

With N64 nintendo stuck with the cartridge format while everyone else was disc based, that put limitations on the software.  Nintendo didn't think discs were kid friendly.  Losing Final Fantasy 7 to sony was a huge blow and it feels like they never recovered the market they lost from that.

The gamecube looks like a purple lunch box and has a silly name.  The PS2 and Xbox OTOH were considered sexier/macho/for people that liked mature titles.

I'd say slight miss (N64)- clear miss (GCN) - home run (Wii) - huge miss (Wii U). 

The N64 did have successful early on in the US, but a lot of that was likely driven by the popularity of GoldenEye, other FPS, and Star Wars games that appealled to teenagers/adults. Unfortunately I think the entry of Microsoft basically took a lot of this audience away from Nintendo. 

lost all credability right there, Halo is as good if not better as anything nintendo can do.

I really doubt it's about competence either. Nintendo has made a game in about 75% of the genres and they do all of them very well. I'd say it's that they don't want to make a Halo or Cod. Their making a shooter, it's more about the potential audience. Their mindset is, hey it's rated E so 7-9 year olds can play it along with everyone else. They don't notice that it really works the opposite way. everyone plays M games and these "hardcore" teenagers-adults won't play anything beneath it. I doubt it's the same way in Japan so I can see why they don't understand it.

Metacritic ratings? oh, those don't count. Guess we'll just have to go off of opinion. I'll give you the benefit of the doubt and say they are equal.

and I could have just copy and pasted lost all credability, but hey, benefit of the doubt.

honestly i don't care if I lost credibility in your eyes if you believe that COD and Halo are examples of good games.  Call of Duty went downhill fast after Modern Warfare 2.  Now it's a simple arena shooter from early 2000 with different skins/guns (heck now they're copying Titan Fall)  Halo may have been revolutionary on the original Xbox system but it's simply another "me too" shooter.  They're both crap games that are cashing in on ignorant "gamers"

And mario was revolutionary on the NES.....

So a ME TO SHOOTER is crap when 3 decades later mario is the same damn thing, run and jump but its not crap.  

Isent nintendo cashing in on ignorant gamers to by rehashing the same thing for 30 years ?

hypocracy is strong with you.

You have to understand Halo wasn't always that much of a shooter and it is a really good series, but calling it better than anything Nintendo can do is a bit of a stretch.
