Spurge is on thread making beast mode today! Any chance of you updating the Wii U pact thread?

New IPs are worth if they bring significant gameplay novelty within a genre; otherwise, why should they matter ?

Going for masters? Very nice. 

If I knew how to do any of that stuff I would update for you myself.

As for the OP, I think they bring up a valid point. But it would be nice to see some new IP's from Nintendo too. Splatoon was a pleasant surprise.

Couldn't have said it better.

New ideas tried on old IP's/characters bring only betterment or new take but not fresh experience which we can get from new IP/characters never seen before, because the old IP/characters are same as old and don't posses uniqueness due to we imagine the character same like old even if he does something different with new ideas.

New IP's create new fan base and new ideas may extend/shrink old fan base, so new IPs are needed to create new User base and new ideas on old IPs are better to extend the existing user base in my view.

We should get new ideas + new IPs in my opinion, with the exception of some games that'd work really well with existing franchises.

You need new ideas to justify the new IP. New ideas are needed far more often than new IP. But you need new IP too.

Splatoon is a new idea that doesn't fit in one of Nintendo's established canons, and slapping a mascot on it would have been like slapping Star Fox on Dinosaur Planet (something that never should have happened). Similarly, Project Steam doesn't seem to fit any current universe, especially not one under Intelligent Systems' umbrella, so it's great to pursue the new IP. Captain Toad is an unexplored character that works great for his new game, which is sort of a "new IP" in many ways. Rhythm Heaven is a great newer IP (from the GBA) that I think would have been lessened by a familiar character.

You need new IP or else your old IP will get muddled and have no consistency as you try to slap a single name and character on every new idea.

Nintendo doesn't have an endless pool of worthwhile old IP. There are only a couple decent ones they own that they haven't revisited at some time in the last 10 years. And some of that established IP simply doesn't sell very well anyway (Custom Robo, Sin & Punishment).

So no, new ideas are not enough. But they are needed.

I agree with this wholeheartedly.

It's a little sad that for gamers, new faces are more important than new gameplay.
