Brawl? Twilight princess?

1) N64 failed because the PS was the obvious choice for a System that gen. It used CD's, could play music, had nearly ALL of the 3rd party support to itself. The N64's games also were way too high in price. About $60 - $70 a game. If you adjust for inflation, that would be $90 - $100 a game. For the most part only Nintendo's biggest fans bought the system.

2) GC failed because of its look, mini CD's, lack of 3rd party support, lack of online, and again the PS2 was the obvious choice for the same reasons the PS(1) was. The GC sold less than the N64 because by that time even the N64 owners moved on to PS2. Both the N64 & GC failed due to many other reasons and had almost nothing to do with games themselves.

3) Casuals don't exist IMO. Different people like different games. COD has just as many "casual" fans as Just Dance. Both also have a core following. The only difference between the 2 are how many games they own, and how much time they spend on playing games. There are WAY more "casuals" than core gamers. Without casuals you end up with GC, XB, or PS Vita sales. You only get 50 Million+ with so-called "casual" support. 

TP was simply a GC port with motion controls tacked on, so I dont really count it, but Skyward Sword I found it to not be a enjoyable as TP, aw hell IMHO its the worst of the 3d Zeldas. Brawl had the worst online experince ive played all gen, and for the amount of delays it got, that was unacceptable for me. MKWii is worst than DD i dont care what no one says. I like the extra level of strategy that DD had, Wii was catered more to I dont want to say casuals but screw it, they made it more accesible which i get, but for me it lost some of the challenge. Metroid, was never into that series so i wont comment. 

Wii series, in general they dont do much for me. both WiiPlays were terrible, WiiSPorts, not really into the mini game comps. In my experience they are lazily made(1st party efforts, being the exception) but even when they are good, i get bored quick due to lack of challenge and much to do. Wii Fit, im not a fat ass and have an actual gym in my building so that does nothing for me. 

WarioLand was good but i hated the forced implemation of the Wiimote, matter of fact, im going to say that same for all of Ninty's 2d plats. motion controls have no buisness in that genre period. THe only game i played that made it somewhat ok, was LBP2. And quite frankly none of the Wii versions hold a candle to the NES/SNES counterparts.

xenoblade, i played for about 2 hours and TBH its boring. Its a GOOD game, i understand that, its just not grabbing me. I heard it gets better later so we'll see.

Mario Party is Mario Party. 

Mario Sports Mix, WTF was that? Where the f**k was my Mario Power Tennis followup, Ninty? Not that rehash crap, hell I would have taken a Mario Golf, since the f*****g controller would have fit those two like a glove, a hell of alot more than soccer or basketball.

Careful with Brawl!

Professional SSB: Melee players were so disappointed with SSBB that they were like:

And thus Project M was born...

Ya think?

No. I know.

You just proved my point. Tetris was bundled with the Game Boy and when it wasn't bundled did little to the NES. When Nintendo was threatened all-around by competition by the wonderswan and by the Playstation, the one thing that kept it in the game was Pokemon.

A core game.

My point is that no matter whether the game is aimed at casuals or at the core crowd, what matters is that the game touch a cord with everyone, so much that everyone needs to have it. And these trends change over time.......

To ask Nintendo to continue exploiting treasures they found in one era is often a bad idea, since these treasures are fleeting and they need to be on the lookout for the next  culturally-relevant idea.

I'm sure fashion has a similar concept...

Don't be ridiculous. It's common knowledge that Tetris is what drove GameBoy sales at launch, and for years after. The GameBoy owes the bulk of its popularity to that launch title -- a launch title that deserves to be mentioned in the same breathe as Super Mario Bros. and Wii Sports. By comparison, Pokémon was just a late-cycle phenomenon that prolonged the GameBoy's life. Sure, modern Nintendo handhelds live and die by Pokémon, but things were different in the early 90s.

Wasn't Pokemon on the Gameboy color not the original Gameboy?

N64/GC definitely survived on the strength of their 1st party lineups.... that was pretty much the only reason to buy them aside from some outstanding 3rd party games like THQ's WCW/WWF games, and RE4 on GC.

It's kind of ironic today because Sony fans used to mock Nintendo fans for basically having only Mario and Zelda and the like back during the N64 and GC days while Sony's success during those gens was heavily reliant on third parties, and now all of a sudden with the tables turned, Sony fans now tout their first party exclusives as their console of choice has lost many 3rd party exclusives over the past gen.
