Well that's just dumb. It's a good argument against IT, but how does that make any sense within the setting. You have this asset, and thus you can't choose Destroy?
The reason I liked IT was because it let the War Assets make sense. Because otherwise they just don't.
Now you've shown that they don't regardless. This game is worse than I thought.
It's dumb because it dissproves IT?
It makes sense within the setting. The more time you take on getting War Assets; the more time we have for the Crucible. If you rush the whole game, without completing any side-quests, that means we had barely enough time to make the Crucible and that your defenses suck.
The reason why it's possible to only have Control is probably because you had the Reaper Brain, which most likely helped the science better understand a part of the Crucible (the Control side). If you had the Reaper Heart, then they better understood another side of the Crucible (Destroy).
Your war assets do matter. Just because you don't see all of them fighting, doesn't mean they don't matter. And you see some of them fighting anyways.
I figured that it happened on the Citadel, and that only the manifestation of the Intelligence and the results of his non-Destroy choices were hallucinations.
If the Intelligence truly didn't want Shepard to choose Destroy, it wouldn't even mention it. Yet it does. It says it's not a good solution but it still offers it. It also offers Control but says that it doesn't want Shepard to chose it.
About the epilogue slides, I'm gonna give you an example. In Synthesis, Shepard dies. Why would the Intelligence show him a world in which he is dead? He's dead, he's not part of this world anymore, he can't see it. The answer to this is: because it's not being show to Shepard. It's being shown to the players.
You can't even tell that the minds are uploaded.
Legions explains it in ME2.
Also, I should point out, I don't accept the outcomes shown in the final cinematic because Shepard isn't there to witness them, so there's no reason for them to be shown to us.
So the world stops moving because Shepard is dead? Really? What kind of logic is this?
And Shepard is there to witness them in the Control ending, he's the new Reaper master consciousness. He's also there to witness them if he survives in Destroy.
