Uhhh not from what I can see. It shows up as Third Wins, so only Robber wins, regardless of whoever survives as well (unless I guess it was something like killer or mafia, not town). I don't feel like digging for the game where I found that out though...
The survive win condition is more like the killer win condition.
Hrm? Doesn't the "wins by surviving" option on the CRC mean it wins if alive at the end of the game? i.e. if mafia or town wins and survivor is alive, they both win?
I dunno what you're talking about, Surviving does not equal the Survivor's win condition. Robber can only win entirely by itself, which is proof enough that it isn't OP. I would understand if it could win with village, but it can't.
This is not bad, but its really strong. The thing about survival roles is no one wants to kill them since they don't care if mafia or town wins. Its always better to kill the enemy. The only drawback to, say, survivor is it can be cc'd to avoid getting killed/lynched. This is hard to CC because it can tell people their roles to prove itself.
