Okay, interesting stuff to compare myself against.
I played ME3 single-player 4 times all the way through. In those, I had imported a game from ME2 for all of them, but I'm playing on PS3 so I haven't gone through all 3 games with one save.
In my first playthrough,
I was a default male Shepard.
I saved Wrex.
I cured the genophage.
I did not shoot Mordin.
I saved the quarians at the cost of the geth.
I won the shootout with Garrus on the Citadel. I was playing a soldier and figured we were equal weapons experts. Plus, I wouldn't insult Garrus' intelligence by throwing a competition with him. He's my best buddy, I won't lie to him.
I don't think anyone died during the game, but just because I didn't notice anyone's corpse before the beam doesn't mean there weren't any there. Also, I never recruited Ashley, because after I romanced her in ME1 and then left her for Tali in ME2, I thought it would be awkward with her around :/
My most-used squadmates were Tali and Garrus, with Liara and Vega close behind I think.
I was actually about the same level of paragon/renegade as the graphic, about two parts paragon to one part renegade.
Over all 4 playthroughs,
I played male Shepard and Femshep both twice. I was a soldier first, then an adept, then an infiltrator, then a vanguard.
I saved Wrex 3 out of 4 times. A game without Wrex is a lesser game indeed.
I cured the genophage 3 times.
I still did NOT shoot Mordin. Shame on you who did.
I killed the geth twice, the quarians once, and once managed to save them both.
I chose twice to beat Garrus on the Citadel, when I was a soldier and when I was an infiltrator. When I romanced him, I let him win, but in the 4th game I didn't do that part at all, because Garrus was already dead. In fact, most of my squad was dead in that game; I think only Jacob and Thane survived the suicide mission. I wanted to see how the game would compensate for all those deaths.
Again, I'm never sure who actually survives the charge to the beam on earth. I remember seeing Garrus dead once, and Javik in a different game. I can't really say more.
Overall, my favorite squadmates are the same as above. Plus Javik, I guess, but somehow I don't use him a lot.
I've been overall paragon 3 times, and once a renegade.
I have beaten the game on Insanity, I have the Long Service Medal; in fact, I have the platinum trophy for the game, so I've done just about everything. I've played hundreds of hours in the multiplayer; no idea how much exactly, but a LOT.
So, yeah. That was fun, going back over the games I played.
