Like Shikki said:
But I really wouldn't mind seeing some of that again, like, a reminder that even if they are here and they are impacting the world they're still technically prisoners in this not-so-utopian world.

I think that's kind of the thing that makes or breaks RP eventually, is the players feeling like what they do matters to the plot. For me, the two most memorable plot events in the game were the Zombie Draft and the Iron Eye Mission. And I wasn't even in on the second mission! But that one really felt like what the characters chose to do--and they had a huge choice to make--really had an effect on the outcome. Same with the Zombie draft, since it felt seriously desperate and like what we did had a significant effect on the world.

So really, I'd like to see more stuff like that. While I know there's a limit on what characters can do to effect the outside world when the setting is a jamjar, I still would like to see some development going on. Things like that don't have to happen often, but having them happen at all is pretty awesome

(Also, my favorite experiment ever was the amnesia one, but that's probably just because it wrecked Loki's shit for all time.)
