Well yeah, there's that. In the end, none of your choices really matter, the ending only changes based on your Galactic Readiness or whatever it was called. Oh, and who the ones you see in the ending cinematic on the Normandy are.
On the note of ending clips, I've got mixed emotions about them in general. On one side, it's nice to see how you affected the world in general, on the other, they can really be a lot different from what you think would happen if you had a personal choice.
Yeah, OWB ending is based on karma, but even as a saint I might think letting the brains experience the Wasteland is a good choice. If they turn out to be a threat, I'll convince them to come back or eliminate them. My karma is good, yeah, but I'm perfectly okay with murdering people.
I'd like for choices to be far more equal as well. Pitt was getting close, but not quite there, Wernher was too much of an asshole to be regarded as any sort of positive choice. An evil character would murder them on the spot. A good character would decide they're too barbaric. I think the ME3 endings were quite nice in this regard. With high enough military power, each choice had its merits and demerits and each could be justified by both a paragon and a renegade mentality. It's just that it messed up the story completely and didn't fit in. Remove the colour coding they had, along with the clips of "who would've chosen what" and you've got total ambiguity.
It's so nice when you can choose the same option in both a good and evil way. Sure, I might not blow up Megaton, but it's because I think it's far more exploitable and I just hate the guts of Tenpenny and Burke. Maybe a Lawful-Chaotic scale would add more flavour to choices.
I think I'm slipping between topics here. Dunno what's wrong with me these days.
