I did, it's so cool!

I am not even surprised it's so great considering it is a mod for Circle of the goddamn Moon (already an incredible game and one of the first I played)

While I'm no purist, I fail to see how it's a true improvement. For starters the weapons feel tedious to use; the shotgun and chaingun shake the screen around too much, the assault rifle and rocket launcher sound pathetic, and the plasma rifle feels... okay, but still not as memorable as vanilla's blaring storm of plasma sound effect. Another thing I dislike is the unnecessary amount of crap being rendered "Hey! look at all teh bullet casings, blood, and shiny effects we added! isn't it pretty?!!?" ...Okay, what does this add to the game besides frame drops? Not to mention the fact that the floor and ceiling blood effects partially float off the edge of platforms, which really takes away from whatever half-decent visual flair they might've had. Oh, and can I mention HOW ANNOYING THOSE DYING IMPS ARE! Seriously! i'm killing evil demons from hell! I shouldn't have to listing to their crying every time one of them lose a leg, what is this Spec Ops: the Line?

Overall I'd say Brutal Doom relies more on visual flair and gimmicks rather than actual gameplay
I don't know, but I do know you could naynay a game that has shotguntesticles and doom frame drops.

Well, besides the gory visual aspect (which lots of us really appreciate), it turns DOOM into a new different game, with the base of our beloved shooter but with totally different mechanics besides the graphical additions (which even if you don't like them, are pretty cool, are a curious addon to a game which looks essentially like it did in the 90's and don't really lag that much). You can play Doom for a while and then, by just loading a file, you get a new game which shares the theme and levels, yet plays totally different. Unload the file, and you get the original experience. A win/win situation if you ask me.
I can see how somebody won't appreciate the excesive gore or won't like the modern features applied to such a classic. But wether you like it or not, it is a great original mod, whose gameplay is superb (I can't think about any FPS packing more adrenaline that BD in highest difficulty).

Also, you can disable the tasty-cles via options if you don't like them (which is a pretty sensible and common thing tough).

"(which even if you don't like them are pretty cool, are a curious addon to a game which looks essentially like it did in the 90s and don't really lag that much)"

While I know that the blood effects are of high quality and took some effort to make, the "WOW" factor wears off after a while and you're left with bunch of useless crap the game has to render. Really, graphical effects should be NOT be a priority for game makers. Sure, it might look impressive at the moment but people will eventually move on from whatever high-quality skin detail you worked oh-so hard on. and correction: They do lag, A LOT.

"You can play Doom for a while and then, by just loading a file, you get a new game which shares the theme and levels, yet plays totally different. Unload the file, and you get the original experience. A win/win situation if you ask me."

As long as said file contains Project MSX and not Brutal Doom, THEN its a win/win situation if you ask me.

"But wether you like it or not, it is a great original mod"

Well... its a great LOOKING original mod...

"whose gameplay is superb"

somewhat decent at best I would say

"(I can't think about any FPS packing more adrenaline that BD in highest difficulty)."

Serious Sam, Quake, Heretic...

"Also, you can disable the tasty-cles via options if you don't like them (which is a pretty sensible and common thing tough)."

*console commands
but yeah good on SgtMark for doing that, now here's hoping he does the same for the blood effects then I might like it slightly more
