Hello, I'm quite snappy looking new official female Shepard in promo art but wait when you see me in the game...
It doesn't look like Mass Effect
If ME3 were a movie, it gives a feel they changed the director of photography and shot to digi instead of film. There's no depth to the graphics, everything's flat, plastic and too crisp, lit in an unimaginative bulk lightning. The game looks like any Hollywood summer blockbuster and that isn't a compliment. Character models were a whole lot better in ME2. Shepard moves without weight to her actions and the only expression they granted her (or him if you go for male Shep) is awkwardly wrinkly angriness. Framerate at least in PS3 version is horrible.

You can choose the overall experience of the game between action, RPG and story. Action concentrates on shooting enemies and the conversations play as cut scenes with no input. RPG is what should be your typical ME experience while choosing the story cuts down action. Of course I chose RPG. Oh dear... The fact there even is a choice for action only tells a lot. This "RPG experience" advances as a shooting gallery. Shepard's combat roll from cover to cover is straight out of Army of Two. Heck, the whole game plays like Army of Two or some other run-of-the-mill EA shooter. Oh, there are gaps to jump over and ladders to climb! And because there are them, there are lots of them. What a great addition to interaction! All the enemies are copies of those seen in any mediocre sci-fi shooter to the point of being childish.

And this is the most important factor where ME3 fails. There's no intelligent depth to dialogue or conversation choices anymore, like dubious moralities you have to live with. Everything's simplified and clichéd, as if the script was pummeled with a dummy bat. Again, just like from any Hollywood summer blockbuster. All characters just annoy. They brought back at least three characters from ME1 I could have done without. I didn't like Wrex much in the first place and he's even worse here while Kaiden is wooden as ever (or, depending on your choices, Ashley, who's just as obnoxious as ever and this time looks like a man in drag). Anderson's VA shouts all his lines without emotion or character's seen it all weariness. Oh dear. And Shepard... She isn't Shepard we knew and loved. She's just angry suckah who everyone keeps pushing and commanding around. Do this, go there, shoot that, come here, follow me, take cover... No no no!
Ah, and why do I get this Sixth Sense feeling? In very early to the demo Shepard flies through a room after an explosion and the world slows down as the camera pans over her knocked out figure. And then Anderson orders her up. And soon she sees an annoying frightened kid who disappers when she had her attention elsewhere for a second. And later she sees the child again. "I see dead pople". Because I'm afraid the whole game happens when Shepard is dead. It's some afterlife dream or whatever. Oh great. Plot twist of the century... Or, the boy is autistic and the whole Mass Effect trilogy happens in his head. Oh great99! I hope I'm so wrong on both counts.
ME3 gives an impression that some mediocre EA inhouse team tried to copy Mass Effect. There's no Bioware's trademark polish, sense of style, wit or suspense. The game suffers from the old trilogy syndrome. The first is good, the second part removes all the bad parts, betters the good points and adds more of them while the third part is Return of the Jedi... So, yeah, we got Han Solo back but even he's a bambling idiot there. Same goes for ME3 and its Shepard.
Instead of what could have been the game of the year we have the disappointment of the year at hand here. Unless demo showed only the bad parts and the good parts are in the final version... But why whould have they chosen the bad parts to the demo as demos' point is to sell the game?
But hey, I probably will get the game anyway, just waiting for a discount. And if I'm wrong, and yes, I would really like to be wrong, I'll let you know.
