Remember Mass Effect 3? The conclusion to a superb trilogy, whose ending left the majority of fans wanting to chew the game disc in angry frustration? Well there's an interesting take on what that cop out of a finale might actually have meant.
Essentially, in one show down with the Reapers (an insect-like alien force intent on chewing up resources and either killing or assimilating the inhabitants), the lead character Shepherd is zapped by a big Reaper beam. This isn't good news - as throughout the game series, you've learnt that exposure to Reapers leads you to being indoctrinated by them.
It was the final choice of the game that really got under the skin of gamers: throughout the franchise, a 'Blue' choice is seen as good, 'Red' is evil and 'Green' is neutral. However, taking the final 'Blue' choice saw you take control of the Reapers and rule the galaxy like a bad ass - while 'Red' killed them and saved the Earth. What gives?
Because Shepherd has been converted - and as such a 'Good' choice for a Reaper drone would be to join them and rule the galaxy.
