Has anyone noticed whether the diplomacy timer ever get shorter? I think that this has happened in a couple of games I've played recently but I haven't been paying enough attention to be sure. Both times I expected an 8 hour + timer and got only an hour or two and in both cases I'd been in my last civ long enough to chalk up a couple of domination era wins from scratch. Am I just playing too many games at once and getting confused or does this really happen?
I've only ever jumped civs a few times (eating barbs), but the diplomacy timer does indeed go up per jump. For me, it's not worth it after 3 jumps. Your mileage may vary.
Unless they've changed it, the progression is: 0, 1, 2, and then I think: 4, 8, 12. And it caps at 12.
