A small thing. If I choose ‘random’ civ, and have the ‘random preferred’ option enabled, I have no way of knowing whether the other player chose their civ (and might have a civ-specific strategy in mind), or whether they are also playing random. It wouldn’t change my gameplay that much but it would be nice to know. For example, in the loading screen you could have the “?” shield beside their civs if they were randomly selected.
Yes, I could pick my own civ (manually at random), and I would then know if I was then randomly assigned a different one, but that doesn’t really feel right.
