I enjoy these.
1) Merc - push out window or let him go
I honestly don't think I would had thought of pushing him out the window, in all honesty. Bullet to the head. Or am I expected to forget what these assclowns did to helpless workers who were in their way? I've killed dozens of these goons getting here, it'd be kinda silly to let conscious get the best of me now. Besides, he's being arrogant and unwilling to help. He had his chance and spat at it.
2) Rana Thanoptis - shoot or let go
I let her go, not really expecting her to get out of the place in time anyway. Let fate decide, since I'm not really sure if she deserves to die or not anyway. I don't have enough details to really make a decision one way or another.
3) Wrex on Virmire - Let Ash shoot or shoot him yourself or are you a good enough talker to talk him down?
While I think I would had talked him down the message I'd get across would be quite different than Shepard. I wouldn't had thought of the "tools for Saren" skit, I would had just argued that we need to SAVE the data if we can. Compromise. Though that isn't really a choice in the game... so.. I guess Wrex dies since I wouldn't be able to think up what Shepard says to him. I'd be the one to do it though, its my burden to bare since I wasn't able to talk him down. Plus Ashley would had probably gotten off on it.
4) Batarian Bartender - make him drink it OR make a scene OR chase him off (he has killed before)
I don't drink so I wouldn't be in this situation. Though if I was, make him choke on it the blink bastard.
5) AI Core - Side with Legion OR Side with Tali (no, you cannot compromise)
Tali. Didn't he take her omnitool or something? I don't see why I can't compromise on this though, lol.
6) Miranda's Office - Side with Jack OR Side with Miranda - Argument was because Miranda wouldn't admit what Cerberus did to Jack was wrong. (no compromise)
From what I understand of the argument I'd have to side with Miranda. Though I'd still scold her for her attitude.
7) Heretics - Rewrite OR Destroy
Destroy. They made their choice, now they have to suffer the consequences. My morals disagree with rewriting them.
8) Tela Vasir - Thermal Clips on the ground OR Shoot the hostage - remember this is not a video game, so that shot has to be very very accurate, and you'd better have AP ammo equipped.
Honestly AP ammo would likely be a bad idea. It makes the shot more powerful to penetrate armor - imagine what it'd do to uncovered flesh. You'd probably blow the poor womans arm off. Anyway, I shoot the hostage. It doesn't have to be THAT accurate. If you were very, very accurate you could just nail Vasir in the head. Doesn't the renegade 'shoot the hostage' just have you shooting her in the shoulder? She can survive that. Plus it'll likely save her life given the circumstances. It isn't like Vasir is going to just let her go anyway.
