No one else took you up ok this, but I will. This list is focused on "1st party" Nintendo titles (I know some are 2nd party or a 3rd party using a Nintendo IP). Also these lists aren't in any definitive order
GC
1) Paper Mario TTYD
2) Smash Bros Melee
3) Zelda Wind Waker
4) F-Zero GX
5) Animal Crossing
6) Metroid Prime
7) Pikmin 2
8) Kirby's Air Ride
9) Fire Emblem Path of Radiance
10) Eternal Darkness
Switch
1) Breath of the Wild
2) Super Mario Odyssey
3) Xenoblade 3
4) Metroid Dread
5) Smash Bros Ultimate
6) Splatoon 2
7) Super Mario Maker 2
8) Fire Emblem Three Houses
9) Animal Crossing New Horizons
10) New Pokemon Snap
There are for sure more Switch games that tickle my fancy then GC games, but I do get why someone could lean the latter. Star Fox, F-Zero, Chibi-Robo, Custom Robo, Wave Race, 1080, Battalion Wars, Wario (land) World, and Mario Baseball are all IP that have love from that era and for many of them have been basically dead since the GC and none of them have a new entry on Switch.
In my case a gamecube top 10 would be something like
1) pikmin
2) zelda windwaker
3) zelda four sword adventure
4) super mario sunshine
5) paper Mario TTYD
6) Luigi's mansion
7) Fire emblem path of radiance
8) super smash bros melee
9) Donkey kong Jungle beat
10) star wars rogue squadron 2
On one hand I have a few games that I still have to play like chibi robo, the 2 metroid prime, eternal darkness and skies of Arcadia which will probably hit the top 10 when I'll play them but other games like f-zero GX, star fox assault/adventure, pokemon Colosseum or pikmin 2 just didn't do anything for me
And the biggest problem for me is that of the game in the top 10 only the top 5 are games that I adore. The rest are games that I liked but weren't anything special.
A top 10 switch instead would be something like
1) Zelda botw
2) super mario odyssey
3) fire emblem threehouses
4) link's awakening remake
5) live a live remake
6) kirby forgotten land
7) metroid dread
8) splatoon 2 + octo expansion
9) xenoblade 2 + torna
10) monster hunter rise + sunbreak
With games like astral chain, paper Mario TOK, pokemon legends and Luigi's mansion 3 as runner's up
And not counting 3d world + bowser fury (port) and neo twewy (not exclusive) who would probably be in the top 3 range. I really like the switch, what can I say?
