Okay, tactical analysis. You are SE, so I assume you're somewhat familiar with the strategies in this game, but I like typing these things out so I have a reference point.
Villager 1 has a 66% chance of being a Tracker / 33% chance of being Jailkeeper
Villager 2 has a 66% chance of being Friendly Neighbor / 33% chance of being Doctor
Right now, this game is a game of
information
. That said, long term, the Friendly Neighbor is dangerous (the Doctor less so, but still dangerous), so the first objective is to locate and kill Villager 1, then Villager 2. Identification of
either
isn't really possible at this stage, we'll have to wait and see what happens on Day 2 to try and figure out who's who. That said, I see two three primary strategies we can employ on Day 1.
Stealth:
Use no mafia powers. No one dies. On the 66% chance there's a Jailkeeper / Doctor, the Jailkeeper / Doctor may erroneously think that they saved a villager from attack. In the event of a Jailkeeper, the Jailkeeper may even think that whoever they targeted is the mafia (low odds ~25% chance). This gives us an extra day to gather information and may screw with the Villagers head.
Guns Blazing:
I use my Rolecop powers, you murder someone; rinse and repeat. We adapt as the situation changes. There
will
be someone seeking us, and there's a 25% chance one of us gets made the first night. In the event that it's the Jailkeeper, one of us gets blocked, but that's not so bad if it's me because it gives away nothing (because you will have killed someone).
Lone Wolf:
Given that I have more powers than you, you can fade into obscurity for the time being and I dish out all forms of pain until the situation changes. This has a 12.5% chance of getting tagged, and in the event of a Jailkeeper tag (admittedly 6.25%); this becomes very ugly very fast. The endgame for this type of strategy will likely lead to my demise with a handful of players left.
That said, I think it's a little too early to select one of these strategies, it's best to see what we can glean from Day 1 and decide later on.
