I like Velthomer and Freege particularly, even though they're part of the large Grannvale state. Verdane definitely felt very bare-bones. It's the most forgettable one for sure. I think a remake though could flesh out all of the countries tbh. Add to their history and culture to really differentiate themselves. I think Thracia and the Manster kingdoms are the only ones that feel like that because of the whole agricultural rivalry thing.
