my first gc game was super smash bros melee.
Mine was Luigi's mansion. Ah... the good ol' days. I miss that game.
what was your second game?
Smash bros. Because Luigi's mansion took thirty minutes to beat (and also since I bought my GC nearly five years ago, I was a little spoiled) my dad went and bought me smash bros which I spent countless hours playing. Hell, I still play it sometimes today. I perfected my strategies with all of my good characters, and pwned Christian and Jarely (my cousins) numerous times whenever i was there. Whenever I start a combo with Marth or Roy, I finish it without trying, the fighting seems almost second nature. Dang I need to stop playing that game.
RESiDENT EViL!!!

Just out of curiousity, what year did you get your cube?
Mine was 2004,i think.First game was...Umm...Oh yeah,Harvest Moon.
1. Phantasy Star Online (i thinks)
2. Luigi's mansion (;_;, i miss this game. lost it though...)
3. Super Mario Sunshine (broke the first, but another, broke that one too.)
4. Super Smash Bros Melee ( i had to reserve a copy)
5. Pikmin
i loved those games...
edit: got my cube a month after launch.
I got my gamecube 2 years ago, and the first game i got for it was starfox adventures because it came in the set. ahh, what a good game that is! i truly forgot what the next game i got was, though.
yeah, i had the starfox adventures. it was pretty fun... but i think i sold it.
