Magnus (the dwarf) has depth too, definitely on par with Raven at least. Virgil probably has the most dialogue of the followers, but that's just as well, considering he's the first NPC you'll meet.Hmm, I might look into buying Arcanum now.
Does anyone know if there are any mods that add new followers with personalities and a fair bit of content or add more content to the existing Followers? I find it difficult to play games with bland companions, and from the info I've seen the only followers with any depth are Virgil and Raven.
If you want more than three followers, you'll have to invest in the Charisma skill in-game anyway (it directs how many followers you can have).
