First off: MULTIPLAYA, SOUPAH TAITO
The unlock rate for shit has gotten really stupid, though. N7 level 70 and I've unlocked characters on 8 different occasions - which sounds great until you realise that unlocking characters and unlocking weapons is used in the same slot. I've unlocked about 10 weapons, and haven't upgraded any of them past rank III. I still only have one sniper rifle mod, 2 assault rifle mods, and blah blah ANYWAY IN THE CONTEXT OF HOW MUCH TIME I'VE INVESTED I HAVENT GOT SHIT
Bad luck I guess.
Almost everything in this game is perfect for a Mass Effect fan. Events
matter. War decisions are sometimes calculated by statistics like
what friggin' dialogue choice you made once in this specific conversation between you and character X after mission Y, back two games ago. There are so many tiny consequences that the game is just so much about the journey as it is about the end. Customisation is BALLSY good and the variety in weaponry blows the previous two games out of the water completely (although admittedly a lot of the guns in ME3 were DLC weapons in ME2 but statistically there are so many new guns in ME3 it wins out regardless).
The way Shepard starts to show cracks is just absolutely magnificent. It was hinted at at the end of Lair of the Shadow Broker, now it shows in full swing and I just love it so much. Relationships between Shepard and squadmates now aren't so one-sided. Mass Effect 2 and 1, most of the time you're talking down your squadmates and supporting them through their character development - in Mass Effect 3, Shepard leans on his/her supporting characters for emotional support, even though Renegade often actively pushes them away. But the writers did great on this angle - the "galaxy at stake" shit isn't an exaggeration. I don't give a shit how badass one's Shepard is, if he/she isn't fazed by the idea of literal trillions of lives being wiped out, I wouldn't care about the character. Even the geth don't have an utter lack of empathy about the Reaper threat. And they're fucking robots.
On a related note,
Mark Meer gets better, but
Jennifer Hale one-ups him again, I think. There are certain times where I think, "Jen really feels this shit, maaaan"
Also, Keith David turns Anderson into something so extraordinary at the end. Words won't describe. Y'all just have to see it for yourselves.
I hope I am not accidentally giving away spoilers. So to protect yourself, do not read my post until you finished the game
I was personally disappointed with the ending because it was very pessimistic. Think about it, Shepard was built up to be the hero of humanity, this badass who could do anything (First human spectre, single-handedly stopped the collectors). ME3's ending went against that completely, making shepard to be human. An extraordinary human, but a human nonetheless. I found the ending shifting the themes of the story in a completely opposite direction. Screw unity, it can't help us. We are all doomed in the end. It is like the saying of misanthropic people that "we will inevitably die alone someday." It is a very pessimistic view, when we were preparing for a hard won victory in ME 1, 2 , and even most of 3, we got his we can't win thing. Basically, Bioware went against everything it built up to be different, or to meet a deadline.
Really? The game was marketed as the end of Shepard's story. The actual ending seemed pretty definitive to me, and none of the people I talked to expected sunshine and bunnies from the get-go.

Also, I don't think it really went against much of the themes in the previous game. The very beginning of Mass Effect 2 showed that Shepard was mortal as
fuck. He/she only survived because some shadowy dude with trillions of credits was willing to put in the science. Likewise, "single-handedly stopped the Collectors" kinda misses out on the idea that Shepard spent the entire game building a team to even have remote chances of beating them. Heck, Shepard asserts a couple times how he/she's just a soldier. There are multiple conversations that have to tell Shepard how he/she is a "natural-born leader" - so although there's a load of badassery, projecting anything more than "cool human protagonist" is a bit much, I think.

I personally don't have so much a problem with the pessimism as I do with the abruptness and lacking of closure to some degree. But although I get the disappointment, I don't align myself with the hate. The whole "PLOT HOLES IN EVERY LINE OF DIALOGUE", "RUINS ALL OF THE CONTINUITY", "MAKES ZERO SENSE" stuff going on at the moment is a load of hyperbolic bullshit.
Case in points: some random guy made ten pages of stuff on a Google Docs supposedly pointing out plot holes and things that "make absolutely no sense", and after glancing through it I could handwave about, say, 4/5ths of it away. That isn't to say there were glaring flaws with the endings, but
actively searching for every hole in the plot will not a satisfied reader make. Half of it was speculative, anyway, things that could be explained away with more speculative crap.
I also think the campaign for a completely new ending is stupid as hell. I wouldn't mind some extra game content for exploring the ramifications of the ending, but when people bring up Fallout 3 and Broken Steel as an exemplar of changing Mass Effect 3's ending, I just want to facepalm. Bethesda didn't make an entirely different ending. They extended the story and made a retcon, jesus fuck.
I'm also in the camp where I think having the Lone Wanderer survive the endgame sort of ruins the meaning of the ending for the sake of extending gameplay, but that's a different matter entirely
