I think Ryo's motivation for letting me take over was that he wanted to see all of his groundwork come to fruition. I fully expect that he'll be keeping tabs on things throughout the game. On that note:
@Zweiblumen: Ryo wrote me a more detailed explanation of what happened pre-amnesia, which included a description of how Crumpled got his new deck. I retract my previous statements about the time it takes to change ownership being greater than the downtime available during the run. That's OOC math, and it turns out that Ryo was well aware of the rules and rolled accordingly. ICly, Crumpled should feel confident in his ownership of the deck.
@Zweiblumen, part II: Noise levels for targets within 100m are 0. Targets up to 1km away are at Noise level 1, although it might be higher the further you go due to trees and other obstructions. A datajack with wireless enabled will reduce the Noise penalty by 1. Personally, I rule that datajack noise reduction does not stack with multiple datajacks. (I am unclear on how multiple datajacks would be of any benefit simultaneously, although I am also unclear of how a wireless benefit can be used to offset a wireless penalty. But let's not go too far down that rabbit hole.) Yes, start with Matrix Perception.
@Malevolence: If you include Centering in the Drain roll then we'll need to keep it part of the IC casting. This is to avoid OOC knowledge of when Centering is necessary/beneficial and when it isn't. That said, you can cast the spell from the privacy of the Rover so that your Centering is not causing a fuss outside where people can see you. Was Ohanzee's Centering method identified? I presume it is singing/chanting/dancing, but a quick search of the Chapter I threads didn't turn anything up.
I am using Google Maps for a layout of the city streets. Obviously the housing will have changed over the next 60 years but we'll keep the roadways largely the same. See here:
