I'd much rather 3 smaller kingdoms of 10 nobles as a foundation than one big kingdom of 30. I like diversity of cultures.
Right.
Because it's way more fun to only have 10 people to talk to in your realm than 30.
I was once a huge fan of little realms. I still do think there's a vital place for little realms: nor do I think giant empires are necessary great either. But I'm getting to where I really think 20-40 nobles, 2-3 cities is probably about the ideal size for most realms. Seems like big and small realms are super hit-or-miss on their ability to retain players.
