Any sufficiently advanced technology is indistinguishable from magic.
@Jellybones: Thats a bad analogy, the more accurate analogy is you'll be perfectly content and happy if you find out that at the end of Dark Knight Rises, Batman actually had super powers, he can read minds, move super fast, and is actually invincible. None of his detective skills were skill and he was trolling you for 3 movies all along. Thus, it made the 1st 2 movies about his humanity and training all pointless since he none of the things he went through with scarecrow or joker actually affected him.
I don't understand what you're trying to say and I don't understand what anyone means when they say that everything they did through the course of the games was irrelevant. Did you not irrevocably change the galaxy in many fundamental ways? Someone said that the ending is Bioware's Shepard and not the player's Shepard, but every choice you make is Bioware's Shepard's options. It's not like you can go off and plan a wedding if you don't feel like saving the Krogan. It's a video game, the choices are binary, you're always choosing from a small handful of options, regardless of whether or not you would personally take any of them.
As for closure, why would you want everything wrapped up in a neat little bow? Do you never want to play another Mass Effect game? This is a trilogy about Shepard, and THAT story was concluded. If you didn't much care for it, that's fine, I didn't like all of it either, but people are up in arms like they were betrayed simply because they didn't like the way the ending was written. They didn't shit on your chest, you just didn't care for their creative work. I wish the internet could funnel this kind of outrage toward things that actually matter.
If Dark Knight Rises doesn't end with a 20 minute epilogue telling me how everyone lived until they died of old age, by golly, I'm going to start a campaign against the Nolans and file a complaint with the Better Business Bureau!
It's always strange to me when people argue that a game can be worse for having additional, but less than exceptional, modes. How many stars should Dead Space 2 be knocked down for having mediocre multiplayer? Should the exclusion of a multiplayer mode have hurt Dead Space 1's score? Should Left 4 Dead have had points deducted because its singleplayer is just multiplayer with bots?
What I care about is how much fun a game is and how highly the experience is recommended. Not the whole package, not every mode averaged together, but whether or not it's worth picking up. If someone visiting the site can't be bothered to read a review and note why a game is getting the score it is, then the fault is theirs if they think they should buy Singularity for its multiplayer component.
