How does the thing works? Do we submit saves as usual along with a PM and you can verify the save or is it more complicated?This is not stated clearly - at least for me - in the game description.
If i got it, a team with all the 9 objectives completed and a finish date say, 1900 AD, will win over a team with 8 objectives completed and a finish date say, 500 AD?
If that's correct, i don't think it's... correct. It would be better to give a weight, like 10 (or 5, 30, 82) turns discount for each objective. Or give X turns for the first, X+Y for the second and X+Y+Z for the third.
Then, 2 workers in the pre-currency stage are a huge price compared to 100g you can pay say, after paper. Maybe you need to think again that mechanic.
