Parvateshwar: I'm speaking as someone who liked the old Dooms and played some of Doom3. I file Doom in the same category as Duke Nukem, games that were fun and totally awesome in the 90s but have failed to keep up with modern shooters. With Mass Effect, Modern Warfare, Killzone, Gears of War, Half-Life, Halo, Crysis, Resistance etc., the market is absolutely saturated with big name shooters from the past 5 years, and if Doom 4 wants to stand out they are going to have to do a HELL of a lot of inventing. As Duke Nukem Forever pointed out, its an uphill battle trying to bring a game from the past up-to-date and to surpass those games. Sure, they have a decent sized fanbase, but that isn't going to compete with the annoyingly HUGE fanbase of those listed games, most of which have sequels, threequels, and octequels that are coming up.
On the other hand, Doom games were awesome and if this is a rumour it would be super sweet. Betheseda already reinvented Fallout and it was pretty damn fun, maybe they can bring this old franchise back and make it better than ever.
As you can see I'm torn, but whatever happens it's going to be interesting.

SimonG: You know what I miss?

Medkits. I don't know which shooter I played recently that had medkits ...

Roman5: This is what happens when you sell your soul to the casual console market and backstab your entire fanbase.

hedwards: That's sort of my thought. I liked the graphics of Doom 3, but it was a real challenge getting the room dark enough during the day to be able to make out what was going on in the game due to excessive darkness.

The original game was a lot better in that respect as you didn't have large dark areas that weren't punctuated by flickering lights.

Verwandlung: It also has regenerating health, the "open" world is very very small, the enemies are never challenging (not even on the hardest difficulty).

There is basically nothing challenging about the whole game, just follow the silly storyline without meeting any memorable characters for 8-10 hours and reach the unsatisfying ending.

Navagon: I really wish people would stop treating Kotaku as a source of information.

orcishgamer: I find it a good source of entertainment. It's my version of a tabloid I guess.

orcishgamer: The duct tape mod was pretty much a requirement to make the game enjoyable.

Drelmanes: Yeah it's funny how they've a lot of high-tech stuff but didn't bothered to make a gun wich produces light by some means. Or why the guy can't hold a pistol in one hand, and a lantern in the other?

Roman5: http://kotaku.com/5851953/doom-4-indefinitely-postponed-following-rages-disappointing-launch

Doom 4 pretty much cancelled.

"Zenimax and Bethesda made the decision based on the "the issues and reviews" surrounding RAGE's launch, which in their eyes has demonstrated "a serious lack of confidence in the project management at id".

"company wide meeting held in Dallas, Bethesda and parent company Zenimax made the decision to "indefinitely postpone" development of Doom 4"

This is what happens when you sell your soul to the casual console market and backstab your entire fanbase.

Crassmaster: Can't have you spending your time in the community of a despicable publisher who sold their soul to the casual console market, after all.
