...and seriously, a video run through? Please think about what you're asking for here. I think after TIM base is when you can check last, or does it roll straight onto Earth, I cannot remember? But you pretty much want a video that starts with me checking the war assets and then playing through the entire final mission which can take about 2 1/2 hours (about 40 minutes from when the beam hits onwards alone). I would also have to wait about a week to even set this up while my galactic readiness creeps down from the recent multiplayer playing, this would also mean I as well as my boyfriend cannot play it for a week. Plus the entire idea totally open to video editing abuse, I could have 0 war assets and just swap the final video for whatever ending I wanted if I so chose to. Even if I didn't it would be claimed so, I am well aware of the internet ability to moves goalposts.
So given the several huge flaws in this plan perhaps you would like to suggest something better, after you do it?
One of the devs on Bioware forums said TIM shooting himself rewards 1000 war assets, other decisions made through the series also matter though don't necessarily direct add or subtract, but adjust requirements, Collector base for example. Maybe they made it easier on PS3 since no ME1 and PS3 seems to be the version everyone ignoring.
