Ooook people calling it a spin-off because it wasn't developed by Nintendo can right go politely somewhere else for that debate.
It's a mainline in the 2D series, period.
Anyway, great score for what's a more experimental game in the series with it's free&flowing mechanics. Did think it was gonna fair a bit better than Link's Awakening, but doing about the same is more than fair.
As for that debate with the Astro Bot game. It's going as well as I expected it to go. (Critically for Astro, Sales will go for Zelda)
