willmcloone: I played the BFG version of Doom 3. You didn't have to switch between the flashlight and your weapon. However, your shoulder-mounted light had limited battery life, so you constantly had to keep your eye on it.
Fenixp: The mechanic is bashed for no particular reason anyway, other than being a bit stupid (like a lot other mechanics are, like lunging 10 guns on you) The game worked quite well with the flashlight vs gun mechanic, quite simply because arenas were lit quite well, and you've only had to use the flashlight when exploring (or killing zombies. Which you actually could kill quite easily WITH the flashlight. Yeah.)
Where I do think it detracts from the intended experience are bits where some alternate source provides lightning for the fights - like imps carried in the shining vats, or the escort bit where if the guy didn't survive, you didn't lose, but you've had to manage somehow. Really liked those, you've probably missed them altogether.
I agree that the mechanics were bashed unfairly. I also agree that most of the time the areas involving shooting were generally lit well enough that you didn't need the flashlight.
