Doom 3 was a horribad game in my books. Id hasn't made anything more than glorified techdemos since Quake 2.
I liked Doom 3. When it was released it had several highlights, such as the blend of survival horror with FPS, the flashlight/gun balance, zero atmosphere parts, great graphics and tons of "extra care" to immerse the player like the PDA with background info, audio clips, scripted events, mindfucks, etc. Remember that nome of that was usual when Doom 3 was released and, along with Call Of Duty, it basically defined the path FPS would take the following decade.
But... unlike the first Doom, it has not passed the test of time. You can clearly see that it has the brilliant mind of Carmack, but not the genious game design of Romero. No offense to Carmack (he´s a hero), but new technologies and great graphics get old, as awesome design and puzzles stay fun. That´s why I still enjoy playing the first Dooms and even the half-baked game that is Quake 1 more than Doom 3.
I expect Rage to be just a better looking version of Borderlands. Won´t make history.
