I purchase a ton of neon-colored rubber balls for the ball trick scanning for the beholder.
I plan to do this as well. At work right now, so hard to update plans.
I see it mainly as a way to ease up on the pressure on the GM for the update itself, and allow him/us to deal with the minutiae on an as-needed basis. It's not that we're not talking about it at all (it's fully implied in what Mami will need to talk with them about), it's that we don't need to cram every last detail into the update itself, when the updates are already getting quite long and troublesome for the GM.
Seems to me that less vagueness makes it easier on the GM, not harder. It's not like I'm giving details on how Mami is to do something. I'm just listing what we want and what we have to offer. Not being explicit about that is likely to get a GM ruling "You didn't say you wanted that."
The beholder is the great threat, we need to get as much information about it as possible. It's not clear to me what harm there is in doing this either.
We don't have much we could actually trade with Kofu, and at their size, they likely don't have a whole lot of money to spend, either. And I can't think of any particularly useful extra actions we could take right now that would matter too much for next month's Tokyo work.
Kofu was described as "about half your size" that's actually a pretty useful size to deal with. They might trade 3 or 4 cubes with us a month.
it's a little hard to pick back up again after dropping it for a month (in terms of relations, not mechanics)
How so? Gossipmonger ought to be easy to drop at times. "Sorry, busy saving Tokyo this month, let's talk next month."
