So, watching the numbers of the WiiU software, I saw that Splatoon and 3D World are rather close in numbers.
4. | Super Mario 3D World | 2013 | Platform | Nintendo | 2.24 | 1.31 | 0.74 | 0.35 | 4.64 |
5. | Splatoon | 2015 | Shooter | Nintendo | 1.57 | 1.29 | 1.52 | 0.27 | 4.64 |
I don't know the precision of these numbers, but they are close indeed. With the Switch already out and Splatoon 2 and Mario Odyssey scheduled for this year, I have to wonder. Which one will sell better? On one hand, Mario is finally going back to the 64 collect-a-thon formula, in contrast to the 3D Land gameplay 3D World used. On the other hand, Splatoon is not longer an unproven IP, and Nintendo will push it a lot to justify their online fees. It will be interesting to see them battle it out.
Also, I leave here the last sales comparaisons that I made: http://gamrconnect.vgchartz.com/thread.php?id=202145&page=1
