It's hard to explain but, it's true there's a lack of new games with other original ideas.
But there's also sequels who are good games and new games too. I would say it would be great if they would continue their main franchise
while developing others new games (even if in matter of time they probably can't).
Mario and Zelda Games are really awesome and Kingdom Hearts too.
We also have great games like Gravity Rush and plenty of others.
