Reasons to reveal to me: Today is my birthday! Also, some people have already claimed to me.
But also, I’ll point out that Dgrazian’s claim is also totally something he would pull as a non-red. Notably, my team’s big strength last game was its excellent coordination, and Dgrazian is very aware that disrupting that coordination by splitting claims would be a good strategy. (Though Dgrazian may quite likely just be a wary red.)
I’ll admit though that there isn’t a good way of differentiating us at this point. So as Dgrazian pointed out, waiting for clues is pretty reasonable. I just didn’t want green/blue to get too much of a head start. Say, by asking every player in game to claim a color.
