The Civ series is still original.
Mirrors Edge. (I know it's already mentioned, just that I ordered it today and am excited

)
Black and white games are original (Although getting on a bit now, they still look BEAUTIFUL, look at number 2 and you will see what I mean, number one released in 2001 still blows me away.)
Assasins creed
Spore
Pyroblazer (basicly a new wipeout)

Well, I think the problem is really the same problem in the film industry. It's hard to be truly original because with the amount of ideas we pump out every year, we were bound to sort of, "run out" of good ideas.
I disagree with this, there are plenty of creative minds out there bussling with ideas, one of the things thats great about humanity.
