Judging by the achievements, I'm probably a little over halfway done with the single player campaign of Mass Effect 3 and all I can say is, man, the ending must really suck. I'm not there yet, I've more or less not had the ending spoiled, but for the amount of hate syrup being poured on the Mass Effect 3 pancake (with vitriol butter) the ending has got to just be the worst thing ever in the history of story telling to offset how much fun it's been thus far.
There are some odd animation glitches, sure, but I just played a bit where you are dropped off on a planet directly into a Normandy (the beach, not the ship) style battle that was straight up awesome. I like the improved shooting, Shepard seems to handle better, and I really, honestly, truly love the multiplayer. It's not the most original thing in the world, sure, but fighting off the horde in the science fictional lens-flared future is great. I'm having a blast with it. It even cribs some good things from Borderlands and Diablo that trigger my ever present loot lust. I've got numbers, sure, but I could always have *better* numbers. That's why they're numbers.
I liked the crew you ran with better in ME2, I think Edie's hair looks stupid in 3, some aspects of the development feel rushed, and sometimes Shepard's head is twisted 90 degrees away from the person I think he's supposed to be looking at, but I reckon he gets shy. There are problems, but so far I love it to death.
I can't WAIT to get so foot stompingly angry at the ending. I bet I'll hate it so much it'll be a contender for game of the year. Hell, I bet I'll love it because I'm perverse like that. I bet I even can guess what it is.
