After installing Origin, playing the demo, and uninstalling Origin, I can say I was underwhelmed.
Say what you will about the manipulative shock value of Mass Effect 2's opening, but it was a lot better than this.
-Like others have already said, the animations are pretty terrible, especially the facial expressions. Anderson might have looked like a potato in the first two games, but he was an expressive potato. The running animation looks like the player is running bow legged for example.
-Ashley's redesign looks plastic. Her face doesn't move at all.
-So now Anderson will be an Admiral despite any choices you made in the past two games? Anderson's on the Council in ME2? Sorry, he's back with the military now! And Leliana can be resurrected by Andraste's cremated corpse while we're at it!
-When did Bioware decide to hire the Capcom employee from Lost Planet who insists every action be controlled by a single button? I can't count how many times I wanted to sprint, only to do a combat roll, or a backflip, or a sidestep. Use some more buttons, you have a whole bloody keyboard.
-Coupled with the above gripe is the motion blurring. Now, motion blurring didn't bother me much in Mass Effect 2, because the only time it showed up was when you were sprinting. Here, half your screen looks like it is tearing if you so much as jerk your targeting reticle.
-The Character creator looks like it has made improvements and missteps. On one hand, the character you create now looks the same in the creator as it does in game, unlike Mass Effect 2, where once the mouth starts moving, you realize you've made a grave mistake.
The problem is I feel like it has adopted some of the problems Dragon Age 2's creator had, namely that while it is easier to make a visually appealing face, it is harder to make a unique one. Most of the faces look incredibly similar to each other regardless of the amount of tweaking. The Hair styles have gotten an upgrade, but this is still Bioware playdough hair.
-Pacing is very awkward. I'm not sure how this will be handled in the full game, but the way it was presented here was painful. James Vega is suddenly well known to the Commander despite never showing up in a game before. The court hearing for your actions in Arrival is handwaved. Suddenly Reapers! Oh, and the Normandy
-In comparison to the explosive start to ME2, ME3 feels awfully quiet, despite the giant robots. Mass Effect 2 was jolting, because your super cool ship was gone. It's like watching the Millennium Falcon or the USS Enterprise going down, it's gonna hurt. Here.... you run along a building, except you are pulled out of the game every five minutes to watch a spectacle piece. LOOK OUT! HERE COMES A LASER BLAST! STOP PLAYING AND WATCH IT! This wouldn't bother me so much if they let you keep control of your character. Instead, the game takes control away from you and forces you to watch the event happen.
-Maybe I'm spoiled because of Uncharted, Bioshock, and Killzone 3's water effects, but my god were the visuals on the waterfront poor.
-The child scene made me more angry than sad. Bioware is above this. I felt more connection in Dragon Age Origins when the elder Cousland's young son was murdered in his sleep than here. The whole thing felt awfully forced and heavy handed, and the mournful piano playing made things blatantly obvious what they were trying to do.
-Default FemShep looks bad. She has the same deformed face as James and Nu Anderson, it looks too flat and non emotive. And look, another red haired green eyed heroine. Never seen one of those before. I would have liked if they'd modeled her after a real person like they did with Sheploo, because they really can't use their own creator engine.
-The second part of the demo was slightly better, especially in pacing. However, it was here especially that the problem of having every action mapped to the spacebar became apparent. With so much cover and items to pick up, one errant tap of the space bar could send you flying into the open.
-I'm not gonna bother trying to talk about the story, because there was pretty much nothing here apart from "REAPERS ATTACK EARTH" and "SAVE KROGAN". And Bioware has shown that they don't really give a shit about your choices if they impact the story.
-Visuals are very muddy. We had a color choice of grey earth, or brown sarkesh, and they both made target identification a pain in the ass, since everything blended together. Still the same low res texture problem that the last game had, and an even more barren graphics menu.
-Before anyone starts moaning that I shouldn't judge the game by the demo, let me make one thing clear: the demo is meant to give you a taste of what the full game is like. If it doesn't work for me, then I won't buy the full game. So don't start whining "but it's just a demo, the full game is far better!"
Last time that happened was Dragon Age 2. And it turned out that its demo was exactly the same as what we got in the final product.
-With that said, I have drawn the conclusion that I will not be buying the full version of Mass Effect 3.
