Nah, the Crucible and the necessity of making the Reapers invincible was pure ME3.

So the part where, in ME1, the ships fighting sovereign say "he's too powerful, we have to pull back", the times in the whole saga "just to bring down sovereign took everything we had and he was just one Reaper", the fact the Reapers have fought for millions of years, the fact the reapers have always been mentioned as god-like and tremendously powerful, the fact that it takes 4 dreadnaughts to deal serious damage (this is codex), and the fact that there are more Reapers than there were of total ships (combined from all races of the galaxy), was all ME3?
