M rated games: What defines a TRUE Mature game?

I've been getting a bit pounded on by people close to me that I've gone to the "Dark Side" and that many people of my faith think of M rated games as "stupid".

While this is the case for most of them IMO, my personal collection don't really into the word "stupid", they are in fact in reality "Mature" in my opinion.

Bad Company 2 with the Vietnam extension might be the most genious game, it makes some good points and is quite entertaining.

Deus Ex is by no in the far reaches of the galaxy stupid, as the game takes brains as well as guts to complete quests and tasks.

Rage, it might not be the most unique game in it's genre, holds some novel ideas on how the weapons, characters, and mechanics function to bring a rarely-seen fluid combat game, it's pure 60 FPS beauty.

Battlefield 3...need I say more? The game is pretty much the pinnacle of war shooters and brings a sense of realism and immersion that would be hard to do in a game lower than M...it's M for a reason.

Binary Domain...again, need I say more? The game while hinges on generic media plots brings an update to what squad shooters have been known for inconsistent graphics and group dynamics. This game brings voice commands, CG-style visuals, and a creepiness to the robots that is almost impossible to pass up.

Resident Evil: Racoon City...This game is not trying to break the mold of co-op shooter games, but rather refine it. Ghost Recon/SOCOM style squad-play with an assortment of zombie-slaying classes and interesting visual and CG dynamics that while still clunky, brings a sense of uniqueness and fun-looking gameplay that games like L4D scratched on the surface.

Killzone 3: Dear goodness...the Darth Nazis are plenty explaining...that and the visuals and gameplay just rocks on what might be the most epic PS3 FPS to date!

Ninja Gaiden III: Love the new realistic take the series has embedded, not as "cartoony" as the last two, the graphics are more vibrant and the replacement of gore from just enemies crying/bleeding to death makes it sound more horrific for me. That and the first-person-like combat of actually feeling like your a ninja cutting people down. That and the assassin's creed looking villain just takes the cake.

Well, I think that's about it for me...don't be a hater.

Thanks for reading!
