Landing the final death blow on Gannondorf in Wind Waker.

Metroid Prime beating it and seeing complete or extended ending.

F-Zero GX so many damn awesome races and the feeling utter defeat when I needed my younger cousin to beat story mode for me. Not a great memory but it sticks.

Pikmin the first time I could get all my Pi min to the ship before nightfall and didn't have to leave anyone behind after seeing what happened when you fail to do so.

Resident Evil 4 all of it except the castle and those one hit kill enemies.

Melee unlocking March and wondering who the heck he and Roy were.

Beating Ikaruga, had use a bunch of lives and continues that first time but beating it was satisfying as heck.

Rogue Leader: Still looks amazing to this day. The best recreations of the major battles from the og Star Wars trilogy.

Melee was what got me into videogames in the first place. Letting the system stay on all night to unlock Mewtwo.

Since it was my first console, I bought a lot of licensed movie games like Batman Begins, Spider-Man 2, and The Two Towers, Didn't know any better, but those were still pretty good.

This console continued the decline for me and like with the GameBoy Advance, I was disappointed with most offerings and the Gamecube would become my least favorite Nintendo system for quite some time. The system made me tired of console gaming for the most part, and when the PC got a bunch of my personal top 10 favorite games of all time I basically left it altogether. At both extremes of the system's life though, there were highlights;

Luigi's Mansion
The Legend of Zelda: Twilight Princess

Luigi's Mansion was a breath of fresh air in the Nintendo game-stable. Though it took a while for it to warm up to me, over time I did get to appreciate it more and more. Finally though I understood that it's actually a classic and Nintendo found a fun, simple yet engaging new mechanic to build upon. At the end there was The Legend of Zelda: Twilight Princess, which was finally a Nintendo game like the classics were. Much of my disappointment with the Gamecube was because of Nintendo's experimentations with it's main franchises. Super Mario was questionable with Sunshine, Mario Kart was weird with Double Dash and Zelda got far from what it should be with Wind Waker. Twilight Princess was a trowback though, and with it's amazing dungeons I immediately liked it. It was too late for my cousins though, they are gone from modern Nintendo.

I was late, very late to the GameCube party, but hey, what an amazing console.

The most important thing for me was that games were known but yet stingers, Sunshine, was Mario but not quiet - still a nostalgic and warm feelings always fills me every time I think of that game.

Luigi Mansion, what a launch title, and cementing Luigi characters forever, All Zelda games, new different form each other, experimental...

Symphonia, RE4, Soul Scalibur great third party support.

I have never loved it but like the WiiU will always have a special place in my gaming memories. Aging with grace and respect!

Maybe it's just me, but I loved Nintendo's experiments with their franchises, rather than going for the vanilla sequel. I'm extremely biased in favour of Gamecube, let it be said, but still. Can't really understand why someone wouldn't like this thing. It had games. It was strong and pretty. It had an amazing boot up sequence.

Note that I said "looked" as opposed to "look", meaning, when I was in college, the system and games looked stupid to me.  The system itself looked like a toy, with bright colors and plasticy parts.  This was in stark contrast to PS2 and XBox which were looking to be sinister and mature.  But as far as games, Mario Sunshine looked like a joke.  The game was based around a gimmik of a watergun, which seemed like a side story, not a true Mario adventure.  And the name sounds "gay".  I hate saying something is gay other than a person who is actualy homosextual, and I hate using the word with a negative tone.  But as a straight male in his early 20s when the title was released, the last thing I would be interested in is something that had "gay" overtones.  Mario Sunshine just sounds over-the-top nice, friendly, colorful, whatever you want to call it.  Childish?  The whole concept made me feel that Mario was no longer for me and my interests.

Then Zelda was a cartoon.  And a Cartoon with big eyes and big heads and tiny child bodies.  And I wept.

That was an omg they actually did that to one of their characters moments. The only thing that comes close to it is what happened to bowser in NSMB.

I googled Gamecube Gay and this came up.

Though to be fair, this one would have been much better.

You were we call nowadays a "bro". Too bad you couldn't look at Eternal Darkness, Resident Evil 0 through 4 and Code Veronica, F-Zero, Blood Omen 2, Geist, Turok Evolution, etc. Oh, all the games that appealed to college bros at the time were also there, sans Halo. You could've been a better person at a younger age.
