BO3 is NOT the industry redefining game that COD4 was. It's not revolutionary at all. It's a great game, but it's basically just COD with Halo and Titanfall movements/themes.

Unless that's what you meant by "better" there's no way this is the best COD ever lol

Until you realize that cod needs a lot of network maintenance along with a movie like campaign to keep up with last year.

I'm not saying one is better than the other, I'm just saying that they seem about equal in terms of difficulty to make

I think the main reason for the criticism is the FPS games have failed to capture the quality of the 2005-2010 era for FPS. 

Halo 2,3. COD Modern Warfare 1,2,3. Gears of War 1,2,3. Crysis 1,2,3. Far Cry, BattleField, Wolfenstein, Borderlands. Games like Fallout, Bioshock etc.

So basically we've seen FPS launch with Amazing Multiplayer, Amazing Campaign with Great Storylines and Atmosphere, and Amazing Horde Modes. 

People expect a Modern FPS to have all 3, when they don't people feel like it's not fully featured. Not to mention Internet Connections have improved, as well as console hardware so they expect the online experience to be better. 

Game doesn't have to be "revolutionary" or "Industry redefining" to be better imo. 

Yea this is definitely the biggest challenge facing FPS. Theirs a legion of people complaining that these games need to change every year, but were far better off them improving the surrounding experience and maintaining the core mechanics, then just changing the game to appease casuals. 

I think, as a few others have suggested, that a lot of the answer in the perceived high standards of FPS right now is that the genre is oversaturated and none of them are doing much to stand out from one another. On the contrary, in my opinion they're often becoming more similar to one another. Depending on the game series/title, sometimes I see that as a step forward, while at other times it's just the opposite. I also agree that Titanfall had/has one of the freshest feels for a FPS game in this generation of consoles.

NO, it's not. Better than the last two, that's for sure. But anything looks good when compared to Ghosts.

As a long time CoD fan, I'll repectfully disagree. 

I don't think so. I'm not fond of the FPS genre, but all are set in similar worlds, with similar mechanics, and similar ideas. Besides Destiny and maybe Battlefront, I don't see many special/unique FPS's. Probably Titanfall did it pretty well, but the mech is just yourself in a bigger body with bigger weapons.
I may sound biased (specially because I am), but after Metroid Prime, I don't really see any much more innovation for the genre. Or Half Life, or Portal. But Portal is just a FPS with puzzles. Still, don't take my comment too seriously, I just see that MP had most of the mechanics FPS have nowadays.

All this talk of FPS's being over saturated, using the same mechanics or themes along with adding little to each title and I'm sitting here dumbfounded by how other genres are also guilty of doing the same, especially when it comes to AI which plenty of games still haven't improved on and hardly many games have passed the difficulty mode from hindering you the player or giving the AI advantages to actually making the AI in general much smarter and gaining more knowledge of basic defence/attack strats.

FPS's may seem like a dime a dozen to some but I see that for other genres just as much, especially this gen which is being touted as the rise of (J)RPGs.
