I'm holding off on 7 myself. I think they deviated too hard from the formula such that it doesn't look like it's even still a Civ game. And while I'm open-minded enough to try it, I wasn't going to drop $70 on a game I had reason to suspect I would dislike. I figured I would wait until it was on game pass, or on sale for $5 someday.

More recently I read that they are going to update the game such that you don't have to switch civs. That's a good start (though I still don't think I will like the era system at all), but reading the initial reviews a year ago I found out that the game cuts off abruptly in the mid 20th century, rather than going to the information age like normal. To me, that is blatantly unfinished, so I'm not planning to get the game until they fix that as well.

Civ is like TOS Star Trek movies: You can mostly avoid the even numbered ones!
