I have three. All from Mass Effect 3. When I first played ME2, I didn't know it was possible to seduce Tali, so I made no attempt to do so. When I played ME3 I made every attempt possible only to find out she'll fall for Garrus instead if you don't do it in ME2. I was never so jealous of a video game character. For the second and third, I did a Renegade play through of ME3 just because why not. I did everything I could to muster up as many forces to combat the Reapers as possible. This meant ensuring that Mordin was not successful in curing the Genophage. [spoiler]I shot him in the back to stop him. I'm so sorry, my Salarian friend. Due to those actions, Udrnot Wrex came to the Citadel to confront me. When he threatened to pull the Krogan support, I was forced to engage him. In the end, I didn't kill him. I couldn't pull the trigger. One of the Citadel security guards shot him before he shot me.[/spoiler]
