Wow, 8:1 to 10:1 would be insane! I mean, there are pc sales to considere, and this game probably got some numbers on pc, at least 500k perahps? so... do you think xbox sales for Nier are around 300-400k?
Prediction: In 5 years Nintendo will Lauch a "Core Mario game" very similar to Astro Bot. That said, many will Ignore Astro Bot existence and say Nintendo created this concept.
