This bit kind of got me.The Cool Kid said:It's not the writers fault if your attention span cannot handle grim for more then 20 minutes.
Take 40k for example; it's never meant to be funny, because billions are dying everywhere, all the time. To "break it up" would be a grave mistake and would only be there to help those who cannot cope with intense atmospheres. Imagine walking around in Amnesia to have a side-kick crack jokes every 30 minutes. It'd ruin the atmosphere.
Dawn Of War was badass for atmosphere if you played any other race, yet the moment you use the Orks...
Orks, orks, orks, orks, orks, orks, orks, orks!
"Ev'ryone knowz red wunz go fasta!"
"I's dead 'ard and ready for stompin'!"
Now I know little else about 40k, but from my limited outside view, it appears Orks are meant to be pretty casual and humourous within the otherwise 'dark and gritty' setting... Y'know, where dark and gritty means people in somewhat brightly coloured armours fighting each other over... Things. Yeah, I don't see dark and gritty in 40k.
All I see is people complaining about a franchise that hasn't been updated in many years. It deserves a fresh reboot more than needs one, as releasing the same game that came out over a decade ago would be... Well, not needed.
EDIT: You're also making assumptions about how 'light heartedness' would be implemented (using examples of very poor ways of doing this... I mean seriously, adding a wise cracking side kick in Amnesia was the only example you could think of?) and basing your argument on those poor examples. There's many other ways you can provide a lul in an intense atmosphere, without breaking flow or the atmosphere itself. A short scene of a brightly lit sunny day with a short, non-combat oriented walk through it is more than enough, so long as it's within context of course. A 'dark and gritty' setting doesn't need to be 100% dark and gritty to remain engrossing, and brief luls in that atmosphere can help bolster the hopelessness a player might feel within said atmosphere when it returns. For a brief moment of gameplay, they were left in an area that looked great, peaceful, allowing the player to take a breath and check his character, equip and use items... Then they can be thrown back into hell for the next section of game.
I remember Diablo 1 being fairly humourous... I found it hilarious when it told me a butcher with little more than a meat cleaver and an apron was way more powerful than me despite me having cleared out three entire levels of enemies by that point. Gameplay in old games is fucking hilarious.
Then again, I'm probably the only person to find humour out of game mechanics...
