What is your favorite gamecube game? It is still my favorite system to this day
I would go with Luigi’s Mansion It was such a bold move by Nintendo have such an unconventional game be the main 1st party launch title. I wouldn’t have thought that putting horror elements (even if they were very mild) into a game in the Mario universe would work, but it created a really fun and unique experience.
Games like Wind Waker, Paper Mario TTYD, SSB Melee, Metroid Prime and Star Wars Rogue Leader are up there as well
