Wii has a fantastic 3rd party game library

The fact of the matter is; the vast majority of gamers, Nintendo gamers included, feel that the Wii failed to deliver on the software end, 3rd party support in particular but also lack of proper 1st party in-house efforts since late 2010.

This is the ruling consensus and while "majority rules" doesn't always constitute a fact, in this case it well and truly does. 

Bold: Debateable, as it could it be argued that the majority of Wii gamers are casuals who were more than happy with what the console offered on this front. We have to realize that us forum-posting gamers are a minority, even on PS3/360.

Italic: While I agree that the Wii's third party lineup was lacking, something being a popular consensus doesn't make it a fact.
