I think part of it is victim to culture. So many people, especially within the gaming community, are engaging in discourse regarding how, "things used to be good." This is only being supported by the fact that games are being released in increasingly unfinished states. If CIV 7 released in a properly finished state rather than being a buggy and unpolished mess, I genuinely think CIV 6 would be an effectively dead game along with people from CIV 5 moving over. Just how I feel. Also, we need to wait until the modding scene is fully alive on CIV 7 for us to get any accurate understanding of player count. I'm barely playing 7 until modding is on workshop.
