That's one of my favorite lines from Shockwave. It just gave this connection between the games and us. Sort of like subtly breaking the fourth wall.
Well they were looking at earth when there were tons of active volcano's and when oil and such were untouched so it was very accuarate but if they came to us know they would not get the kind of energy they scanned for
Most sentient races would probably be rather self-centered, we'd certainly find a solid metal planet strange.
Lots of potential slaves, lots of oil, lots of molten magma, lots of rivers, yeah there is energy there. He didn't know it, but freakin Unicron was also there. I'd say he is a source of raw energy..
They may be robots but I doubt even they can live on a star (high temps and winds and all). And I thought personally that the reference was a given, especially with him discussing things such as the earth creature Grimlock was "fused" with.
Yeah. There's no need to actually mine energy. One can simply gather it. A good example would be what The Fallen did.
