We're basically on the same page, Indirik, but I'm playing devil's advocate for the sake of keeping the discourse objective.
For once, playing on several isles, even if they are pretty much identical, allows for different experiences. You play a tourney knight on one continent, on another you play a priest of a new religion or an infiltrator. Makes sense.
Again, I can come up with no redeeming arguements for having two characters on the same isle.
Playing a lot of characters is likewise kind of cheesy. There is no way you can invest enough time in, say, 5 nobles. Obviously at least half of them are there for power hoarding.
