I played it out and found out that it was repetitive to play the same game again and again when everything is done. I would often play it again until I realized that it got kind of repetitive. A reroll made me open my mind a little particularly in random and get me a totally new civilization and area. I get to learn new ideas and I start implementing new strategies as I start a new game and I prefer it this way because I've gone that one more turn route and I wouldn't gain anything. In civilization 2 for example, I would get stuck in the same place and wouldn't move up a line in one more turn. That doesn't always happen but I guess the only way to stop it is by getting an achievement you're truly proud of, get to the one more turn phase and play it out until you can no more. I realized I couldn't do that because there's many new opportunities with a reroll.
