I never like this question as the breadth of measures and variables is so large, so it sort of depends.

If you're talking about sales then games like Wolfenstein, which were fantastic, but undersold.

If you're talking about game quality then you'd be looking at things like Dark Dreams Don't Die, Destiny, Drive Club, Destiny and Watch Dogs.

If you're talking about game quality relative to the degree of marketing and hype, that really is less of a debate, and the frontrunners are Drive Club, Destiny and Watch Dogs. Fortunately for the publishers those three games will all wind up selling well when the dust settles - but the franchises will not last long if something significant isn't done to bring them up to scratch in the second iteration.

Haven't played Destiny but dang I guess it was a huge disappointment XD

Watch Dogs by far.

Wii U and Xbox 1's poor sales. The PS4 needs strong competition to push it onto greatness but it just doesn't seem to be there.

agreed. i own watchdogs and driveclub on the list. i didn't obsess over either for weeks before release. just calmly bought them when they came out and enjoyed the hell out of them. Watch dogs co-op missions online are some of the best online gaming ever. great fun. driveclub is just out and it's very good also. 

people who over hype things will always be dissapointed. 

I'm noticing a common theme here. The letter D. :P

Destiny for me I expected something better from bungie

For disappointment

whts wrong with it?

sunset overdrive. its not multiplatform.
