One thing that really gets me is the choices you have to make. Every previous game goes to pains to explain to you why something is needed, what it does, what you have to do, etc. Think Vigil on Ilos explaining the Conduit or the plan to take out the Collector Base. There are no explain 'push magic button' solutions. It is all explained, all understood.
But when the the Starchild gives you the choices there is no explanation. There is no explanation of what exactly the Catalyst is, who created it, why it looks like it does. There is no explanation why, if the Catalyst is needed to activate the Crucibil, the Starchild can't do it. There is no explanation how jumping into a stream of energy coming from this giant weapon will (or could possibly) merge every organic and synthetic in the galaxy. Or how grabbing some circuits will give you reaper control. Or shooting some tank destroys them. They all seem metaphoric.
Shepard proceeds to the Catalyst virtually uninhibited. Three Husks and one Maruader (that shoots you once, c'mon!) - token resistance to make it not seem to easy (if you just walked in you'd be suspicious). Then absolutely no enemies inside, clear run to the console. Shepard just accepts everything, like it's a dream. The Illusive Man arrives and his 'power' of you and Anderson seems like an attempt to convince Shepard that control is possible. If Shepard is resolute, Anderson is shot in attempt to weaken them. If Shepard still resists they fight off this attempt and 'TIM' is killed. 'Anderson' then dies and 'Hackett' informs Shepard that it doesn't work. This seems like more attempts to break Shepard down, which seems to work as s/he collapses.
Then - VOILA! - a floating platform (where is this tech from!?) comes out of nowhere and takes Shepard to the next challenge. This time, we are presented with a more sympathetic face - the little kid. Who attempts to convince us (and often successfully, be honest!) that destroying the Reapers is wrong, you NEED synthetics (despite saying he made the reapers so synthetics won't become a problem!), then plays on your possible feelings concerning friendly synthetics. He then tries to sell you control and (despite saying TIM could never control them) he says you could control the Reapers (with NO explanation why!) and there will be peace. He then proposes synthises of organic and synthetic as the best option (which also happens to be what a Reaper is!). And all you have do, apparently, to fulfil your choice is some simple action like jumping in a beam of light, or shooting a tank. How it works? Who cares, Shepard? You can 'stop the Reapers' with one simple action.
To me this is so obviously an attempt to decieve Shepard. And every choice is an attempt to draw Shepard away from destroying the Reapers to ideas of control and synthesis (the mantra of TIM and Saren). Couple this with the fact that when you destroy the Reapers you wake up...
I mean, c'mon!
Also, I'm curious as to whether you get the Stargazer scene if you choose the lowest ending and destroy the Reapers it destroys Earth. I mean, wouldn't that put a dint in the chances of old man river being around in the future to tell the tale. And why would any child want to hear the tale of how Shepard ****ed up?
Anyway, the above stands out to me and coupled with everything else and the fact that the game makes so much sense up UNTIL THIS VERY LAST, WEIRD -ASS, DREAM-'LIKE' SEQUENCE! As well as all the BW teasings. There has got to be something going on here!
Also, I think this thread is starting to lose it's focus. We're starting to overanalyze things like the artwork image, the trees, etc. I think we've made all the solid points. Now we just need to keep bugging BW on Twitter about it until we get an answer!
