Just feels like you're looking for different ways of saying that you should be allowed to play the game. Which you are. Just not for free.Agree, that those are valuable. That's why I used "also" in my initial post.
If you didn't buy just because you can't play as one civ, that is what's being added. You know that without needing to playtest extensively.
The feedback should be on whether the implementation doesn't break the game's feel or difficulty curve, compared to the current version. You cannot do a comperative test without first playing several games with civ switching, which is a thing you don't want to do.
