Actually got to finish the game myself, which required a little late night rundown. Still, I couldn't see myself starting the final mission and picking it up 18 hours later.
To start off, I have had an amazing time with the game. It was really only today when things became frustrating like being disconnected from EA servers during multiplayer and my game freezing twice. Still, I'll say it again, the character dialogue and interaction is amazing. Garrus has amazing lines, as well as others we've mentioned. I made sure to check all of the Normandy for the dialogue bits.
That said, this leads into what has bothered me for some time: the DLC and multiplayer. I won't go into detail because, again, it has been discussed, but Javik actually had some plot driven moments for an "optional" teammate. I really don't like the randomized pack system for multiplayer because I feel like it limits my potential. I have so many shotguns, but I don't use them. I want to use another assault rifle, but the three other rifles are still at Lv 1 whereas my M-8 Avenger is now Lv 6. Thankfully I've unlocked a few other classes I want to try playing.
You can completely see the manipulative nature to Mass Effect 3. I mean, I will never pay money for multiplayer packs, but there's a sucker born every minute and so there's another source of revenue added to the game. I collected more than enough assets in my 40 hours, actually to the point I nearly had 7,000. With 3,500 at 50%, I would definitely have to play a little multiplayer to get the good ending for...
It's true what everyone has said about the last ten minutes. It's like running a marathon, but not crossing the finish line because you tripped over a beaver. It's not that you didn't finish that's so perplexing, it's that you tripped over a damn beaver. IT DOESN'T MAKE SENSE!
It hasn't ruined the game for me though, and there's a lot of ridiculous crap going on for both parties as we've discussed. Here's the thing though, it really didn't have to end up the way it did, even with the same plot if they were so inclined.
SPOILERS!
If they forced an ending on you based on prior actions, that's kinda what people expected, right? I mean, if you're going to have multiple endings anyway. If there were only two, I think people would indeed be pissed if they were stuck with the bad ending, but I guess we would have to say, "It's how you played Mass Effect, it's your doing."
I'm starting to ramble as it's late for me... and I have taken quite some time typing this, so there.
EDIT: Oh wait, WAIT! Was about to log out, but I remember the other
