Lazy developers are just doing the same on consoles these days, and it too will eventually cause a backlash as people get sick of the genre.
Most of the intelligent gamers I know have been sick of the FPS genre since the mid 90's. There are very few shooters these days that have any quality.
Lets take an example of a newer FPS that has tried to bring something slightly new into the genre. Borderlands...
My wife has been playing Borderlands mostly for the last month or so since I picked it up. I lost interest in it within the first few days after I bought it. Why did I loose interest in it? Because within the first few minutes of installing it and playing I noticed a few things. A: The physics in the game sucks and is almost non-existent. B: Interactivity with the environment is Non-existent. In the first town you start in you find boxes and barrels and all kinds of things really. I saw a beer bottle on top of a barrel and thought "hey, target practice", and then I shot it. At first I thought I missed because nothing happened, so I got closer and shot it again. Then I unloaded a entire clip directly into the little glass bottle sitting on top of the barell...and nothing.
So they put all that work and all that money into making a game with a great loot system just to kill the game by having no interactivity with the environment. I thought that was extremely lazy of the developers and it just killed the game for me. The only things in the game that you can have any effect on are the enemies. Everything else in the environment is static. That just doesn't cut it for me in a shooter these days when we have computers capable of putting characters into living interactive worlds. Worlds where shooting glass will make it shatter differently every time you shoot it. Worlds where if a target is standing behind a wooden door or wall you can still shoot it because , NEWSFLASH, bullets go through wood. Borderlands has nothing even remotely close to these aspects, yet Half-Life 2, which came out years ago, has all of them. Farcry has these environmental effects too, as does Halo to some extent. Crysis and Crysis Warhead have the best environmental and physics effects I've ever seen in a shooter.
How come that kind of love and detail and attention to the surrounding environment weren't put into Borderlands? Lazy Developers...which is surprising because 2K Games usually puts out good work.
The "long story short" of it though is that the FPS genre is by far the one area of gaming that is still, in my eyes at least, stuck in the stone age. The whole genre needs a serious injection of innovation and love put into it if it's going to make a serious come back.
Btw, Halo was a Doom clone too, so technically we're still in the Doom clone era. Then again wasn't Doom a clone of the original Wolfenstein? Not sure which of those came first now, it's been too long, but whichever it was, all Fps's can be considered clones of it.
