I think the thing that bothers me the most about the ending, is that no matter what you choose, your crew is stranded on some far flung planet and all the mass relays are destroyed. It also bothers me how Shepard dies in all of them. I was prepared for endings where Shepard dies. I get it, sometimes sacrifices have to be made to save everyone. But he's dead in all of them? Oh, so there is one where he *kinda* lives? Ok...except as I said earlier, your best friends on your crew are now somewhere on jungle planet X, you'll never see them again, and everyone that YOU made BELIEVE in your cause to come help you is now either dead from the battle or stuck in your system. BILLIONS of people from different species stuck in one system, with one habitable planet with now very limited resources. And that happens in all of the endings! This is the reward for everything you've done in the past three games? I loved ME1. I loved ME2. I loved ME3 until the last 5 minutes. Those last 5 minutes have just about ruined the entire series for me. With ME1 and ME2 I immediately started a second playthrough to make new choices, and going along with ME3 I was already planning ahead for what choices I would pick on the next run, but now? Fuck that. If those bullshit endings are all I have to look forward to, what is the point? Would it be so bad for there to be endings where the relays and Citadel *don't* blow up and people get to go home happy? I mean, Jesus fuck, I just gave the quarians back their homeland and now they are all stuck here? I just had to kill all the geth that I just made sentient beings? I doomed every turian and quarian that came to fight for me to die of starvation (because of their dextro-amino needs)? I cured the motherfucking genophage for all the krogan, but now none of these badasses get to go home and make babies? Oh, and your best friends and love interest back on the Normandy are now who the hell knows where, never to see you again (even if you lived). Fuck. That. Shit.
I read someone defending this bullshit with the line of "Its about the journey, not the destination." Well to that I say bullshit. The destination is pretty goddamn important. The journey can be all kinds of awesome but if the destination is shit, would you even want to make the journey in the first place?
An analogy. Your friend invites you to go on a road trip with him. You've had some pretty damn good road trips with this friend before, so of course you immediately agree for another adventure. Then he tells you the trip is actually going to be a year and a half later. Well, thats ok, because the last two trips were awesome and he keeps telling you that this one is gonna make those other ones seem lame in comparison. So you patiently wait a year and a half, and then it gets to two weeks before the trip, and your friend calls you every other day to pump you up about the trip. Finally the day arrives, you and your friend set off on this trip. Admittedly you are having a great time along the way. You are eagerly thinking this is the best trip by far. Then, your friend lets you know that you have almost reached your destination. You still don't know where you are going, but your friend keeps assuring you that EVERYTHING has been built up to this, and you've finally arrived!
So you step out of the car, and then your friend proceeds to kicks you square in the balls as hard as he can.
So despite you having a blast on that trip and other trips before? Would you want to take that trip looking back, knowing you were gonna take a swift kick in the junk? Would you ever want to go on more trips with that friend now that your balls have retreated into your pelvis? Hell no you wouldn't, and that is exactly what I feel has been done here.
