No this was more like a question for the sony fanboys out here "If Mario is so childish,how come its the second best-selling franchise?"
strangely in Ubi's 20 Best selling franchise in 8 years list,not a single PS exclusive series is listed
Oh, Come on. That hardly qualifies as "Next gen console discussion" either. This is not "Is Mario/Nintendo childish or not" discussion.
The only explanations I see for Ubi's claims are:
1. They are full of **** <--- Possible
2. They split the franchises/excluded games in such a manner that their games come up higher.<---- Probably what happened.
If the data is correct, Mario should still be first best selling franchise so that would be a more potent question .
