This is, again, not the point of this topic. But to address it anyway:
First of all, no, they're really not. As in, DA:O wouldn't have a perfect system merely by getting rid of the gifts. Secondly, my objections to FNV's reputation system are mostly not bugs, they're poorly implemented mechanics and an overall system that affects little.
Re: DA:O, clarify. Re: FNV, you're asserting that faction-specific approval ratings
cannot work. Again, clarify.
Thirdly, the only thing Paragon and Renegade affect for the choice is Shepard's persuation ability. Which is independent of all the other choices you made with the quarians and geth. So blaming is as 'simplistic' when it in fact had nothing to do with such a scenario other than act as a skill mechanic is really very silly.
Who said anything about blame? All I said is it's too simple to act as a persuasion mechanic. They tried that in ME2 and all it did was compel people to align with one side or the other throughout or fail to resolve the loyalty conflicts.
In fact, does Paragon and Renegade even affect that? Or is it just reputation that affects it? Which would mean Paragon and Renegade has utterly and completely nothing to do with the choice whatsoever? Which would make you pointing fingers at...well...not very smart at all?
No, but again, this is irrelevant to the issue at hand, which is whether such decisions should boil down to a single climactic dialogue wheel with immediate results or "the falling of small stones which starts an avalanche."
