Oh really?

This is NOT a complete list, but here is Nintendo's perfomance over the last gen and half way through this gen. I am positive that I can add many more into the list. Compare the number of games and critical reception of Nintendo's offering against Sony's, and you will see there is simply no competition (in favor of the big N)

Well I am not using personal opinion and taste. I am using an objective criteria (i.e that is number of games across genre and quality). Evidence suggest that Nintendo has Sony beat. Sorry friend

You should look at my list again. Sony has beaten Nintendo hands down.

By what standards? You aren't exactly putting forth a convincing argument

Even though your list has the higher average; what strikes me is that it also depicts the OP's thread title. It shows Nintendo's incredible reliance on the same mascots and franchises, almost every new IP they have attempted in the past decade has been tiny budget casual fare like Wii Sports or has become very niche (W 101) and unable to carry the platform.

As much talent as they have and as much heat as MS and Sony get for all their shooters and racers; Nintendo can be conisdered a pretty boring developer all in all and they are well known for not tasking risks on behalf of their audience or other developers who could provide more variety in their software library.

Well, I agree that Nintendo needs to extend their franchise base beyond what they have now. That's why their "Garage" initiative is an exciting prospect with Splatoon being the first game of such initiative.

@bold, I disagree. Excuse my bias, there is simply no single publisher or developer that has their fingers dipped into so many genre and have the same qaulity as Nintendo. Unless you can point one out to me

And that's not what I said at all; my point is that with Nintendo's, by now famous, poor relations to 3rd party developers, they are missing out on a lot of potential games that could offer more breadth in the overall software libraries of their consoles.

As for your comment itself; I think Valve and Blizzard, and probably more, could be said to have the same quality games that Nintendo do, not as broad though.

With the poor support we're seeing Nintendo get; it falls all the more on them to provide this variety and try out new concepts and IP's (that aren't five dollar projects like Wii Sports and Nintendoland or contain Mario, Zelda or the other mascots for once and that don't end up as niche releases).

At no point did you mention 3rd party relations in your original comment. The topic at hand is , which you expressed in your original comment, is extending nintendo's Ip base

new ips are not the problen neither are old ips.

the only BIG problem imo is that they have two platforms to feed and not enough manpower to do it properly.
