Back when #OcarinaOfTime was about to release (and when it was in development), I recall it was referred to as #Zelda4 by the video games magazine I read. #LinksAwakening wasn't counted, as it was perceived to be a spin-off title, similar to Super Mario Land.
I was curious about what the consensus is in 2025, but it turns out search engines just return Four Swords Adventures when searching for "Zelda 4".
When asked a question, Google's AI claims that #ALttP (#Zelda 3) is the fourth game.
