Pretty much this.

As were practically every Xbox 360 game. This doesn't affect his point. The XB360 had the best third party support last generation, and it also had HUGE limitations in disc capacity. Most RPG's required something like four-discs to contain all of their content, and many multiplats suffered from compression on the 360 vs. PS3. 

He was opposing the argument that the Gamecube's mini-disc was the main reason why third party games were less frequent on Gamecube, and that is blatantly false. 

@OP

Nintendo's problems with third parties had to do with liscensing and control over content. It's been their problem since the SNES era. As soon as viable competition came,  they abandoned Nintendo because it gave them more freedoms in the development of their games. Now third parties expect to be pandered to and given every resource possible to subsidize the cost of development. Nintendo being a fiscally conservative company doesn't play those games unless they can get a benefit from it without a huge risk. 

Look at the post I'm quoted. Compare double layered games to single layered games isn't fair IMO.

Regardless of how successful they were, that was their goal. The first Wii U focused E3 contained Nintendo parading third-parties on stage, announcing Assasin's Creed, Mass Effect, Call of Duty, etc, etc. They chose to remain with the PowerPC architecture so that 360 and PS3 ports were easy to do. 

They had a fallen out with third-parties because they didn't give them special treatment over their competition, like EA with Origin, and Japanese third-parties always begging for publishing deals (Square-Enix, we're looking at you.) 

Nintendo is at its best when it ignores third parties and does what it must do with or without them. The N64, SNES, and Wii are some of their most iconic consoles, and that is because they were able to gather exclusive experiences that just couldn't be found elsewhere. That is the Nintendo its fans want it to be. Nintendo fans like Nintendo games, regardless of what other people care about. We like our Mario, Zelda, Metroid, Smash Bros, Mario Kart, Xenoblade, Fire Emblem, etc, etc regardless of what fans of other consoles like. Nintendo's problem this generation wasn't that it didn't have third-parties, as they haven't had third parties since the SNES, and even then it was a tense situation. Their problem this generation was that they didn't come out and create the games that their fans buy their consoles for and tried to get the games that their fans didn't have. Zelda U should've been a priority, not Assassin's Creed and Mass Effect ports. People play those games on other platforms. 

He wasn't. He was comparing double-layered (Wii) games to double-layered (360) games. 6.8 GB is not single-layered (4.7 GB is.)  His use of "single disc" was not the same thing as "single layered." 

Nevermind. Misunderstood. Sorry for that :D

That handle was a last minute addition. I took mine off. And the system can be assembled normally. The problem with the console without the handle. You can't grab it. So you picking it up with one hand is not an option. Unless you have larger hands. The cube design kind of forced the handle. WHich screwed the look.

GameCube was a good system. To be honest I personally didn't mind the design, it definitely is memorable at least. They could have made it look less toy like fairly easily though, that was a bit of a problem. 

Unfortunately Microsoft coming into the industry basically caused the no.2 spot to become split. Otherwise Nintendo would've sold 45-50 million GameCubes fairly easily IMO.

They should've just agreed to put Windows CE (or whatever it was that was on Dreamcast) on the GameCube and made an ally of MS rather yet another competitor. - 

At least the GameCube had good third party games like Resident Evil 4, REmake, Zero, 2, 3, Code Veronica, FF Crystal Chronicles.

Gamecube, Wii U (Gamecube HD) strategy just doesn't work for Nintendo. Third parties are the bread and butter for Xbox and Playstation but for Nintendo success has come only when they tried to make a mass market device and support it with their own first and second party software. Differentiating its product from competitors, rather than imitating them.

The size and storage of the discs, the colour of the consoles or design are just silly conjecture based hypothesis. I had the original xbox. It was a monster black and green brick with some big ass controller at launch. It got more 3rd party support as a new entrant to the gaming world than Nintendo did with Gamecube. Go figure but without the old purple lunchbox and size of the discs hypothesis.
