1. Stand off between Douglas and Sam. That was fucking epic. Wish they would have explored the theme more though... the first three games suffered from a lack of personal level of character development (although their attempt to do so in Double Agent ended up backfiring BADLY). They should have given some credence to Shetland's philosophy and frusturation, and it would have even been better if they could carry that out in the later 2 games, where Sam has to deal with a corrupt government led by beaucrats as well.
Around 30:30
Spoiler: I prerred the outcome where Sam shoots Shetland than put away his gun. It makes Shetland's speech completely baseless and worthless (as he tries to shoot Sam... I think), and it makes the following line sound like a corny joke (get it? He didn't actually shoot him!). On the other hand, if you shoot him, it solidifes Sam's badassness, loyalty to the government, how much of a soldier he is, and how much he is willing to sacrifice (he shot his best friend, a fellow soldier he fought and bled with). It also makes, not only Shetland's words fuller with meaning, but Sam's as well (Shetland has changed so much, after becoming so cynical to almost the point of insanity, that he isn't the same friend Sam knew).
They should have definetly exploited thsi in Double Agent, yet they fucking failed to do that. Hopefully they could in Convictions... but I doubt it.
2. "Wow, killed by a ninja... cool", in Chaos Theory XD
I'm not gonna list any other interogations, as there'll be too many: Just watch this and part 2:
3. Shooting the lady in Pandora Tommorow, in Jersualem. That was really sudden, and it made you really feel like Sam (if you're the type to just do whatever the game tells you) when you're ordered to just randomly shoot that lady and do so.
3:00 ish
Guy didn't do it =/ But you see what kinda position you're put in the first playthrough.
4.
3:00ish
"Medals don't help me sleep at night Lambert"
... so fucking GAR.
Other stuff I didn't mention. Killing one of Douglas' honchos by ripping through the paper wall in Japan. I liked to then kick him into the bath... I loved the Bank Robbery mission in it's entirety. First playthrough you can't possibly anticipate about the laser that comes up so you don't put on your Thermal goggles and BAM, all of a sudden you're in a suspenseful shootout/hiding/escape.
