since this is a spoiler forum i'm going to spoil away (that sounds dirty...)
but has anyone been able to unlock the last set up dialogue between Shepard and The Illusive Man?
i've heard that you have to select the paragon/renegade options (the options on the left) every time you talk to that indoctrinated fool (mars, Citadel on both accounts etc...) but haven't been able to confirm it.
my guess (and this is pure speculation) judging by his confusion on the Citadel before you light his ass up he was about to say "yeah, your right Shepard. fuck these Reaper fools!" and proceeds to destroy them without eliminating the Relays in the process...which kind of sucks.
however the fanboi's (including me) are hugely outraged by this. however i've heard the excues "well now we can't have a Mass Effect MMO!!!"
the difference between those fanboi's and myself (on this topic) is that IF an MMO were to be created (i'd jizz....a lot) you can still have the setting prior to the beginning of Mass Effect 1, however beyond the date of which the Prothean Ruins and the Charon Relay was disocvered...
Mass Effect takes place in 2183 and 2185...so put the MMO say 2173 and you'll be OK
but still, how the hell do you unlock the 3rd paragon/renegade option at the end of the game? (before your 1 of 3 choices that had nothing to do with the other 2 games)
