Now, after I've found out that Port Royale 3 was published recently, and because I didn't really play anything in the last few days, here is another 'Musings' post: Caribbean MMO.
Yes. I know. PotBS. I know. I even played it. But no, thanks, it's not what I want. What I really want is an MMO where ships are for transporting people and goods (well, maybe an instanced fight here and there, but certainly not ship battles) and you have a normal person view, just like you have in every classical MMO. You can visit and explore the islands as well as a part of North and South America. You can fight pirates, soldiers, merchant bodyguards on land, you can explore Mayan ruins and you can learn the magic of the Indian shamans. You can take the one true religion to the natives and steal their gold. You can search for treasures marked by big red X-es on old treasure maps. Etc. Etc.
Combining this with a character background system such as the one found in Darklands, introducing new game systems for plagues, ship blockades and four sided pvp.. I'd love it.
