So, I just completed my pure Renegade playthrough. Spoiler: The End -Upgraded the whole ship, recruited everyone and made them all loyal. -Romanced Miranda. -Intentionally got Thane, Zaeed, and Morinth (picked her over Samara) killed on the mission. Sent Mordin to escort the surviving Normandy crew. -Tali died while holding the line, as a bonus. I like Tali, but not in this playthrough. She doesn't fit in a Renegade crew. -Wiped out the collectors, but saved the Collector Base. So...yeah, I'd call that a successful playthrough. Now that I've completed a pure Paragon and a pure Renegade (both males), I'll be going back and doing a more ambiguous Paragade female, and a Renegon female, too.
