I like to think of the GameCube as the oddball out of all of Nintendo's gaming consoles. As it was the first Nintendo console that was able to play game in CD format and their first foray in the 6th generation console era. There are mixed feelings towards this console, but most of it is relatively positive. I think that most will agree that, while it's a good console, it doesn't live up to the high standards of excellence of Nintendo's previous consoles or influence. It also had poor online support capabilities and there were only like three games that support it.  
 
I do like it's design, it's certainly distinct look that lives up to it's title. The controller also had a crazy look and button layout that I personally liked. It did have hardware superior than the PS2's and rivaled that of the Xbox. It did have a decent library of solid titles, but I personally believe that it had a weak library of truly exceptional titles. The exclusive titles I was a big fan of were The Legend of Zelda: Wind Waker, Metroid Prime, Metroid Prime 2: Echoes, Eternal Darkness: Sanity's Requiem, and probably Star Wars Rogue Leader: Rogue Squadron II. I would've mentioned  Viewtiful Joe and Resident Evil 4, but they were later ported to PS2. I personally consider it to be the weakest out of the three consoles of the 6th console gen ere, and I'm going to get a lot of flak for saying that from a lot of Nintendo fanboys.... Oh, well.
 
So, what's your opinion on the GameCube?

Had some great games. It's small, and had an interesting controller. Played it more than my Xbox but less than my PS2.

Don't forget Smash Bros. Brawl. Main reason to own one.

Pretty good games, cool design, but a terrible controller.

The gamecube had a lot of great games for it. It didn't have much going for it as far as multiplayer was concerned but that didn't hamper my enjoyment of the many great single player titles.

gave me a lot of fun

A lot of wasted potential IMO, but it still had some great games. Twilight Princess is one my favorite Zelda games, and I'm playing Skies of Arcadia right now and it's awesome.
 
Plus RE4, Metroid Prime,etc.

Mediocre overall.  I can go back and play SNES and N64 games and feel the nostalgic factor; Gamecube is right at that point where it's too recent and thus doesn't feel that fun to go back to.  Same with PS2 and Xbox. 

It was just there .  

Favorite console I think.
I own more cube games then anything else.
I still adore the controller and I just got off the GC playing some PSO.
 
Wuv it.

I didnt play it as much as I did my xbox or ps2, but gamecube had some really good games that im glad I got to play

Introduced me to Pikmin and the Metroid Prime series. Also it had a handle on it. A FUCKING HANDLE SO YOU COULD CARRY IT AROUND. One of my favourite systems. 

The games seemed to vacillate between either extraordinarily unique (Eternal Darkness: Sanity's Requiem) to incredibly mediocre (most of the games that came out for it). What it averages out to is just that: pretty average. Super Monkey Ball and Super Smash Bros: Melee were great party games and Eternal Darkness is one of my favorite games of all time (as well as having the second best Harvest Moon) but I never owned one and if you asked me to name other games for it, I couldn't really say (Metroid: Prime, Mario Sunshine...great). Like most of Nintendo's recent systems, it was defined by its few unique games, but brought down by the slew of mediocrity that came out between them.

Great 1st party and exclusive 3rd party content but utter shit when it came to multiple platform ports. 
Also I thought the little disc were really cute.
My favorite Gamecube games are:
1. Pikmin 2
2. RE4
3. Metroid Prime
4. LOZ: Wind Waker
5. Eternal Darkness

It's my favorite console after the N64.

" @DoctorOptimist: Don't forget Rogue Squadron: Rebel Strike.  Probably my favorite game for the console.  Rogue Squadron needs to make a return. "

" Don't forget Smash Bros. Brawl. Main reason to own one. "

I think it always had a bit of a bad rap because it was seen as Nintendo being small and cutesy with their design but I personally loved it. Naturally it falls second to the PS2 but it produced stuff like Smash Bros, Luigis Mansion, Mario Sunshine, Twilight Princess, Metroid Prime(s), Res 4, AND Wind Waker, which is definitely one of my favourite games of all time therefore a decent console. I just think it'll always be perceived in a bit of bad light for its design more than anything.

It's definitely cube-shaped.

it was my personal favorite of the three consoles. not because of third party support, no. in fact, that's what my playstation 2 and xbox were for. but, it seemed as if every exclusive, even aside from nintendo's standard faring, found unexpected ways to floor me. i can't even begin to recount how often a title like killer 7 or eternal darkness left me with a sense of joy after an initial playthough. it delivered such wonderful enthusiasm, game after game. to this day, i don't understand why people continue to complain about nintendo's little lunchbox. in retrospect, its lineup was something special.

I have been going back and playing some Gamecube games lately, namely Wind Waker, Tales of Symphonia, and Metroid Prime 2. I do like the design of the console (even though I'm playing these on a Wii) but the controller is hard to get used to. Having a button on top of the right trigger but not the left trigger is just silly. I found it fine until Metroid Prime 2, where I've been wrestling with the controls. It's probably just because I'm used to proper FPS's now.

One of my favorite consoles, I still remember picking one up when I was around 13 and getting Pikmin with it, fucking awesome.

Almost everything about the Gamecube was dumb. The controller was ridicules, the system itself had a weird toy-like design, the small discs, no DVD play, and the purple being the standard. It has some great games, but a dozen enjoyable titles doesn't prevent the system from being one of the worst modern consoles. The Gamecube looked like some off-shoot Chinese plug & play.

It had some good games but it killed the Nintendo fanboy I once was.

" bad games "

Best 4 years of my life.  
Brilliant controller and awesome set of games.

I used the cube for playing with friends, and saw many people carry it to public areas to play (like a lounge on college campus).  It was a fine system for gaming with people in the same room, and I think it was a success because of that.

I'm not sure what you mean by "It didn't live up to the high standards of quality".  It seemed like it was a quality product to me; I played it for many hours, and it was never as fragile as the PS2 (several of which broke on my brother, leaving him in a lurch until he could fix or replace it).

dreamcast > gamecube 
 
that is all

Better than the Wii, that's for damn sure. 

I like my gamecube alot, great console. I liked it even so much that it completely replaced dreamcast  for me. Gamecube has a nice combination of stuff i liked about n64 and stuff i liked about dreamcast.  Tons of great games and it's just a very fun little machine. And it's the only real way to play gamecube games, the wii totally doesn't count. I'd say gamecube is the best  console that nintendo has ever made. It has the whole "Capcom 4",  it has my favorite Mario Kart, Ikaruga and few other awesome dreamcast ports and I think Super Mario Sunshine is alot better game than Mario 64. And I love the minidvd's and the overall design of the gamecube. And purple is just very unique color for a gaming console so i give it also some points for originality.  I think gamecube is really underrated, even more so than dreamcast. And that is alot said from someone who is actually pretty big sega fanboy.

Most of the "great" games got ported to decent consoles so w.e. It did have Wrestlemania x8 though with the freakin' nWo though!

I liked the controller, but I never really played my GC that much. 

Wish I still had one. I miss playing Resident Evil and Wind Waker, my two favorite games.

Gotcha Force.
 
That is all.

I love my GameCube. The Wavebird is my favorite out of all controller designs; it just feels right in my hands.

I still like the design of the Gamecube itself. It was just a big block with a strong handle, and it made it feel like the system would never break.

My least favorite Nintendo console, it didn't really do anything to innovative and wasn't a huge improvement on the N64.

I loved it, i didn't have many games for it, but the ones i had i enjoyed a lot.

The Gamecube was amazing and I still mine from time to time.

after the ps2, i think it had its fair share of classics, and one of the most perfect games ever created: metroid prime. it is perfect, and don't you deny it. well ok, perfection varies between persons, but it is certainly flawless.
