I'm thinking we should map-claim. here's why:
-as of now, scum have a lot of info about the map, as they can all see each other.
-there are more town than scum, so while the map-claiming helps both factions, it helps town more
-allows for smarter night moves, because we know what rooms don't have anything good in them.
-We can safely save up money because "oh hey, there's a gold room a nearby, I won't waste my money on this!"
-town can avoid both trying to buy the same thing, causing an auction which results in a waste of money.
cons:
-scum have a better chance of pillaging someone who has a lot of money, or is in the same room as scum.
-scum have a better idea who has the best roles, and so make better kills
the second one is a real problem, so I'm suggesting not revealing exact location of ourself, or things purchased (or lack of things purchased). The main things we should claim are where good rooms are, and maybe what items are in places.
