My only Shepard that matters, until I get the urge to play 100s more hours of Mass Effect (MIGHT happen this year, just sayin!).
-Spacer (wanted a mom, more connection to exploration)
-Sole Survivor (liked the thought of being the one who makes it through anything, one way or another)
-Paragon, Paragon, Paragade (inflexible about Reaper and War related matters in many cases)
-Saved the Council (under the hope and confidence that Sovereign was doomed anyway, but there ought to be galactic stability during this time of war prep)
-Cured the Genophage with Wrex and Eve (the Krogan as a SPECIES are easy enough for me to forgive, despite their actions, and I feel mostly those who outright avoided most Krogan content would feel otherwise, or those who just don't want the danger of this specific species around at all)
-Romanced no one, Romanced no one, Romanced Kaidan
-Peace between Quarians and Geth (but a skeptical one; I do not speak of this peace with huge hopes, only care and concern for coexistence)
If you wanna go with the colors, I started off almost entirely Blue (but not entirely), then ended up being mostly Blue, and then torn between Green and Red on different matters. Red with the Reapers, and Green with Rannoch and Krogan (imo 'Blue' for Krogan is more Cure + non-ideal situation with leadership).
I have a feeling that a future hypothetical game might have me go outright for Green, then holding back for certain things and making me opt for Blue or Red instead. In most cases overall though, I avoid the Red, I avoid the Renegade, and I don't find it useful or necessary or something I'm passionate enough to go for. Yes, I didn't even punch the reporter. But I also find that pure hope or faith is delusional and dangerous. Just the more grounded character examples for ME1 had me go the hopeful Paragon route, and the more clearly defining examples of ME2 had me go "Yeah, I'm Paragon here". ME3 challenged me in ways that I think players underestimate (IMO), and had me question preconceptions, one way or the other.
