Sinobi is sharing interesting stuff recently. Now it's Mario & Luigi RPG 4's turn.
Sales:
2003■GBA「Mario &Luigi RPG」438.781
2005■NDS「Mario &Luigi RPG 2」417.391
2009■NDS「Mario &Luigi RPG 3」745.701
2013■3DS「Mario &Luigi RPG 4」¿?
The series sell around 400k, but the third entry exploded. The blog says that the feeling is that Mario & Luigi RPG 4 will fall on sales and return to the 400k level.
For Pikmin 3's impressions you should wait a little. Probably tomorrow we have some comments.
