Sakura Samurai and Jump Superstars are Nintendo published! Looking at the list, they've actually done a good job. They just need to improve the average quality. I can see some gems on the list though.

Worth what?

The people are saying that because these IPs can't reach the big success and greatness of the Mario and Zelda franchises for example. Because of that the people will continue to say things like that but of course to create a brand that is such as big as Mario is pretty much impossible. I mean: If you like him or not you know him because everybody knows him...

For comparison, Sony Computer Entertainment has published 143 brand new franchises since 2001!

My source is wikipedia and I'm sure I made some mistakes, but whatever, you get the whole idea. =P
Someone in the mood of making such a list for Microsoft Game Studios?

Many of these games don't recieve near the amount of hype a lot of these Sony and MS titles recieve, so thus they don't exist in the eyes of many of these "hardcore" gamers who thrive on hype..

And they would have sold better if they just put Mario on the box.

Comparing them to MS isn't an apples to apples comparison because when you are new in the market, everything you publishbh is a new IP. 

Just like people are pointing out with the Nintendo list, how many of these are "worth it"? 

I think you already know this or rather realized this, but the point is they do indeed create new IPs or are open to new IPs. I also get tired of all the whining that they are only Mario and Zelda, or even Pokemon, Donkey Kong, Yoshi, Kirby...wait a second if I stopped there it would be impressive. Some of the most iconic franchises. People need to find something new to gripe about. They do try new things. Publishing Bayonetta 2 is...um...quite a departure. While not a new franchise, nor their franchise, they are open to the risqué. It's a shame their tent pole IPs destroy most other IPs in terms of quality and imagination.
