I think it was a disappointing game even if you disregard the parts the drama focused on.
Terrible fetch quests, clearly unfinished reworking of the ME2 planet scanning / normandy overworld, makes the #1 decision in ME2 irrelevant (save / kill base), does the same with the rachni choice from ME1 (the game just invents a new rachni queen if you killed her), removed all neutral dialogue responses, had a lot more scenes without any player choices or choices where what you picked made zero difference, harbinger is nowhere to be seen, illusive man is a undermined as a character by the fact that he was just indoctrinated all along and most importantly nothing you do has any significance at all in the final mission. War assets are pointless.
Just look at all the things that made the ME2 suicide mission great and then realize that none of that is there in ME3's final mission. It's a culmination of everything you've done throughout the game with multiple tough decisions giving branching paths, coupled with great pacing and very strong character focus.
Now I'm disappointed all over again. Bummer.
It's the thing they've mentioned on the bombcast before. The whole diamond situation where everything spreads out, and is as wide as it can get during the middle parts, but it all comes back to meet at 1 point at the end. The fact that they mentioned on the last bombcast, that the Walking Dead did this too, makes me not wanna play it.
It's fucking bull shit, why make a series so much about choice, and not create...I dunno, MULTIPLE ENDINGS. It's not like that's a new concept. There have been many games in the past that had multiple endings, and outcomes depending on your choices. Just look at friggin Chrono Trigger.
The Mass Effect series set up this universe, and game franchise where I thought my choices would matter in the end. I'd understand if they had to bring it down to reasonable expectations, but the way they handled it was complete and utter nonsense, and even after more clarification of the plot holes with the EC, I still think it sucks.
