2 million in its first weekend, right before the holiday season.
For comparison's sake, and these are VGC numbers, so take: (NA + Europe + Japan: Launches aligned)
Galaxy 1 - 526,910 + 153,922 + 260,993 = 941,825 units.
Galaxy 2 - 705,394 + 227,478 + 340,397 = 1,273,269 units.
3D Land - 302,878 + 143,853 + 341,904 = 788,635 units.
No 64 or Sunshine since there's no VGC data on them, and no 3D World for reasons obvious.
The games that I think are the closest to compare would be 3D Land and Galaxy 1, seeing as how those two games launched within the first year of their respective system's life cycles and went on to sell throughout their generations If VGC can keep it close, since I know we don't track digital and we count physical copies sold to consumers instead of shipped to retailers, Odyssey should have the best launch ever for a 3D Mario game. That we know of.
