I wish the two games were staggered, so they didn't start and end at the same time. It would be nice when the yellow vs blue ended the other one was half-way done. Just my opinion and something to think about.
We will introduce 6-hour rounds for red-vs-green game soon. So the fee rate will be raising with the same speed in both games (0.002316 % per second), but there will be two red-vs-green rounds finished during one yellow-vs-blue round.
