It's simple, they don't advertise or barely advertise any of their games because they don't need to. 80% of their games end up selling in the millions, and 20% of them sell like 10M+. So what's the point of spending cash in advertising their games when they already sell well without it..
Predictions for LT console sales:
PS4: 120M
XB1: 70M
WiiU: 14M
3DS: 60M
Vita: 13M
