Be careful--there are two very similar victory conditions. Make sure it's "victory conditions do not apply until after X years" and not "X years have elapsed." I set up a really cool epic game with something like 15 years of peace required and didn't take effect until after 30 years--except it was 30 years have elapsed, so my game ended just as things were getting interesting.
