Forum:Survivors after reapers

Hi there. I have a question: How many survivors do you think were there left after resolving the Reapers threat? In game, they speak about millions dying (on Earth) and so on. By looking on the state of the ruined cities and the sheer number of Reaper forces it seems that populations were reduced from billions to millions. It seems to me that surviving races can easily become prey to "untouched" races which are about to invent space travel. So, do you think that there can be a "rennaisance" of the old races or will they go into decline?
