It is obvious than those on Wii are more mainstream oriented, but for all that, are they totally uninteresting ?

Last gen (wii+ds):

Mario games (platformer): 7
Zelda games: 4

Don't know about the other franchises, but that is a lot.

I think I have played that game with the dog with the hat. Does anyone know what game that is from? :D

"Mario games (platformer): 7"

On Nintendo DS : Super Mario 64 DS (HISTORIC PORT!), New Super Mario Bros
On Wii : Super Mario Galaxy, New Super Mario Bros Wii, Super Mario Galaxy 2

Which are the 2 missing main Mario games ?

PaRappa the Rapper.

Maybe someone else already pointed out, but yes Microsoft is the worse of the 3, as they limit the number of franchises they have. Also, im pretty sure there was an Xbox live Fable game in 2D. So you can rise that to 4 if you want.

I do agree though, Nintendo is highly criticised by something that the others seems to do worse. In the case Microsoft is clearly worse. Sony has a habit of creating new franchises every gen since most of them end up failing and they try something new, but i would say that they are the most of the safe side. It all depends on what they reveal for the PS4. If the uncharted series continues or gets axed like Jak series did and if the other series carry on. I guess they milk God of war already though. 2 per system.

Those stats are heavily skewed.

You can't just stick Mario in a cart and claim it to be a different franchise. Also, you're missing quite a few games from the Nintendo list, I'm not a huge Nintendo gamer and even I can see some obvious emissions like Mario Party and Paper Mario. Factor in handhelds and that list is going to look VERY different.

The number of games isn't even the problem either, most of the IPs you listed on the Wii are at least a decade old, whereas the ones in the Sony and Microsoft section are fresh IPs.

Nintendo milks the character Mario but that's about it. They don't milk their franchises but it might seem like it if you just look at the amount of games and ignore that they are spread across several platforms.

Nintendo is in a difficult situation when it comes to their old franchises. The fans expect new entries in their favourite series. I guess Nintendo could stop producing Zelda games but they would get slaughtered for it and whoever made the decision would have to flee to another planet. If they stopped using Mario investors would flee and the company would crash.
It's the Nintendo curse.

It's not like Nintendo never makes new IP's though, but if you want more of them then you'll have to support them. We vote with our money after all.

it's not cause they fail.  Jak, Ratchet, and Sly were all successful yet they moved on to new things
