So I ended up gaining the loyalty of everyone on my team except for two people - Miranda and Tali. I'd completed Miranda's mission, everything went fine, and then she and Jack had some stupid fight that I broke up in Jack's favor, because really, Miranda was being a bitch, so I lost her loyalty there. Neither my Paragon nor my Renegade was high enough to talk her down for the rest of the game, so she remained "normal" on the loyalty scale. At least I had all of her abilities unlocked, which really was the most important thing in my mind. Tali, on the other hand, did not like that I used the evidence against her father in order to clear her name, which I thought was absolutely ridiculous. I wasn't going to let her go into exile for something that her father had done, so I went against her wishes, which of course cost me her loyalty. Whatever. I was so peeved that she would be that upset with me for trying to help
her, you know, the person on my crew, that I pretty much completely disregarded her from then on. I was a little bummed that I didn't unlock all of her abilities, but I got all of Legion's, so no harm, really. Speaking of Legion - would either choice (rewriting or destroying the heretics) have given you his loyalty? He had no real opinion, and the geth consensus between destroying and rewriting was pretty close, so I'm just curious. I chose to rewrite them because I figured, hey, the more geth on my side, the better.
May I just say that I love the interactions between Joker and EDI? Especially during the part when you're controlling Joker (though that part other than that was absolutely terrifying, ha).
Apparently doing any missions after the Collectors attack your ship will cause you to permanently lose some of the crewmembers who had been stolen. I did not know this, and went ahead and did the Project Overlord dlc before heading out to find them. Whoops. The two notable crewmembers that I lost were my Yeoman and the female engineer. I was saddened by this, as I really liked all of the banter between the female and male engineer (no, I don't remember their names off the top of my head).
I ended up losing Tali at the end, which, as cold as it makes me sound, didn't bother me too much. I was glad that it was her, and not Miranda, to be honest, as they were the only two I could have easily lost, having not had their loyalty. I took Garrus and Jack with me to the final fight - holy huge terminator, batman!
I really liked Arrival - I could tell right away that I couldn't trust Dr. Kenson. Not sure what it was that made me feel uneasy around her, but when she turned on me in front of the artifact, it was one of those "I KNEW IT!" moments. I was glad that I got to take her down. Sorry, lady, that you don't get to see the arrival of the Reapers. Really. My bad.
Overall, I tried to play as much of a badass as I could bring myself to do. I'm definitely higher on the Renegade arm than the Paragon arm, although they are both in their 3rd sector. I had reached the third sector of Renegade before Paragon, and was admittedly kind of disappointed when I squeaked into the third sector on the Paragon arm and saw that my scars were slightly less noticeable than they had been before that.
I have to admit, a few of my decisions were largely based on what would give me more Renegade points, especially after I chose to rewrite the heretics and saw that doing so gave me 30 points of Paragon.
In fact, that was largely why, in the end, I chose to save the Collector vessel instead of destroying it, which honestly, I didn't want to do at all. I really wanted to destroy it, and I really really didn't want to give it to Cerberus, but as stupid as it may sound, I wanted the points for Renegade...now everyone on my ship is questioning the decision I made. I've thought about going back and redoing just the end if I have a lot of trouble with my crew when I start ME3, because I don't want to have to deal with any insubordination or trust issues, but we'll see. It might not even be that big of a deal, but with this game, who knows.
