Exactly this.. ..He has some nerve to act like his company is above reusing games/assets/systems...its the a similar Mario with a new coat of paint each generation.
I think you missed his point. He was talking about one event, but it's basically true at any event. Go to E3. Go to TGS. Go to Gamescom. Basically all you will see is game after game that, visually, looks the same, and all of them mostly play the same too. Either a FPS or a third person FPS.
He of course isn't saying that those games don't have a place, or that current franchises should be stopped. No, rather, he is talking about when folks create NEW experiences. Basically - he is saying that when new experiences are being crafted, developers are too focused on what is currently popular and trying to mimic that instead of being creative in their own right. He feels that, slowly, game development is being lead by the folks who maintain the budget, rather than the folks who create the product. He hopes Nintendo doesn't go down that route - and for the post part... they absolutely do not.
Yes, their mainstay franchises are obviously all samey. They should be in many respects - they are franchises, but WHEN Nintendo releases something new - rarely is it like anything currently on the market. Animal Crossing? Nothing like the Sims and that is the closets comparison there is. Pikmin? Nothing like other strategy games on the market. Splatoon? Again, an original concept in an existing genre. STEAM? Same deal. Wii Sports at the time? Yup. Brain Age? Yup.
I think his main points are rather clear: The industry lacks creativity when crafting brand new products and ideas. Not inherently that the franchises are bad, but that too many NEW big budget games try to mimic those franchises instead of creating their own path. It's the Jim Sterling Spaghetti Sauce argument all over again.
If Miyamoto was specifically talking about sequelitis, that's a different story. But he isn't. It really seems targeted at the creativity presented in new games. I mean, Destiny is a brand new IP, yet it visually looks and plays like other games on the market. Sure, we can talk for ages about how unique it is, how it's an MMO that isn't really an MMO, or whatever else, but reality is that it looks and feels like games we've played before. It doesn't FEEL original, as it were.
