I completely agree with the state of gaming now, especially with the FPS genre. Seems like ever since Halo game out, the genre shifted that way for the most part. Then developers just played it safe with that and never tried other stuff...
No more games where you didn't have to choose which guns to carry and you could keep them all (like Goldeneye and Duke Nukem), no more extremely absurd weapon combinations (Goldeneye again with the P90/grenade launcher combo in the Jungle), no more complex level design that would leave you lost for a while (Doom and Quake)...
Painkiller and NecroVision have been close to keeping this alive, and hopefully Bulletstorm and Rage do the same, but I sadly think that the future of the FPS genre is going to be a ton of the same rehashing, and the same for other genres too...
