nah that's not opinion, that's objectively true. Everyone has their own tastes and grown up in different eras, so they appreciate originality differently than say someone like me who has been around since before nes. (I also think this gen is more original than any previous gen. It's exploding with indie titles and new ways to play)

I think this is what an oppinion is : Objectively true for the person who is talking ;)
I do not consider my oppinion as false even if someone disagree with it; they are definitely true to me.

I also agree with you, we saw a lot of very original and good game during this console generation.

while pixar does have some amazing creativity in their movies, their past couple of movies really werent all that original cars 2, brave (great movie, nothing original), toy story 3 and now monsters university. they seemed  to go down the same route in the past 4 years. 

Yes it has. But only in certain cases. Like movies, there's really no new story to tell, but studios can tell the same stories in different ways, mixing techniques and genres etc. Games are the same, even if the tech gets better. For example, if a holodeck is made, sure games will be innovative, but in the end, we'll still be playing the same ol games and the same styles of games, just in a different way.

Gaming has lost a lot of originality but not all of its originality

To a certain extent, yes. When a Mario game comes out, we know it is Mario. When a Pokemon game comes out, we know it is pokemon. They are, like many long-lasting IPs, working with a formula. Gaming has come a long way. From the days where FX chips were the greatest gaming technology to the 1080p, 60fps we have today and the games grow with that technology. They grow old together, making their own advancements or in some cases backtracks.

I think games will be new again when the group of developers from the start of the NES days are retired or sadly deceased. So yes I mean Sakurai, Miyamoto, Iwata, Horii, Inafune, and so on. That is when new, younger creators ,just like Shiggy Miyamoto or Yuji Horii once were, to take the reigns of game companies. Recall when Iwata was appointed CEO of Nintendo of Japan along with Reggie? Nintendo, then, was known for the 64 and gameboy and Yamauchi didn't know where to take the company? Iwata was chosen and after a rough but successful start(NGC/GBA era) he brought Nintendo into the DS and Wii era and changed gaming just as the NES changed gaming 25+ years ago. It is a cycle, a cycle that we haven't started over just yet.

I have played a game in which I was a petal... that says it all if you ask me.

I don't think gaming has lost its originality, it's just that developing is getting expensive, and not many people can afford to let a game bomb. I doubt that games will get more original next gen because... well look at the next-gen games shown at E3. They don't really usher in new experiences, and focus more on new technological advances. 

At E3, there really weren't that many "new" experiences, but that wasn't the only problem. Most of the "next-gen" highlights are either corss-gen (MGS5, Watch_Dogs, Titanfall), and probably weren't truly developed with "next-gen" in mind, or they're sequels/New IPs that play extremely similar to 7th gen games, almost to the point that they're downright uninspired (Driveclub, some Nintendo games, and pretty much everything EA showed sans Titanfall). 

I think developers next gen will focus on making games bigger and more expansive, rather than trying new concepts. Look at Killzone 3-> Killzone PS4 (forgot the name). Bigger world, more things on screen, etc. That is the kind of change that devs will probably aim for next gen. 

SEGA to me, was the last major console manufacturer to take risks with its games. The Dreamcast had Shenmue, Jet Grind Radio, Seaman, Space Channel 5, etc. etc.

SEGA was the best console manufacturer, and when they got out of the hardware department, no one took up the mantle. Now we get generic game after generic game. Nintendo was KIND of innovative with the Wii, but took twenty steps back with the Wii U.

Generic after generic, eh?

I think most people are a bit blind sided by the AAA industry that they won't notice the great games, conceptually, that are literally biting their noses off. We've had Limbo, Flower, Journey, Portal, Slenderman, Amnesia, Bayonetta, Yakuza and a host of other indie, less known, very interesting games.

What's originality after all?

A completely NEW concept, never before seen? Is it exclusive to just this?
Or can we talk story, character, setting, mechanics, feeling, mood etc?

Thing is that I've noticed that gamers are somehow clamoring for the next BIG thing...which, if I were to ask, I doubt anyone could tell me what it is. Or what they'd themselves imagine it to be.

Demon's Souls fleshes out its world by careful and subtle construction of the environment, with great care as to what you get out of the experience...and people call the world derivative and boring, without even having scratched the surface of its beauty.
People have stopped appreciating...everything. It's a bit sad.

Heck, when's the last time you've played a pirate sailing the Caribbean seas, stealthing through the undergrowth of the jungle, immersing yoruself in history and atmosphere, and even engaging in naval battles?
And people comment it's just another Assassin's Creed and it needs to die...forest and the trees.
