As for potential servers, I'll start with the ones we've had so far:
The design of the first server is very reminiscent of Bladerunner/Cyber Punk.
The server with the dungeon has something D&D-like for me. Could also be due to the troll.
Then we had Red Herring. Here I see by most of the designs and the creepy elements quite comparisons to Lovecraft or the general Cthulhu stories, although in a more morphed form.
We can't say much about the Calypso server, since it's still in the works.
At that time Alex was also probably just in the direction of a High Fantasy server on the way, at least I would interpret it in such a way.
Then we have two more historical servers based on Egypt and Rome.
And of course the Warthogs server.
Accordingly, I could imagine the following servers:
A Sci-Fi server in the style of Mass Effect, Star Trek or the Traveller Pen&Paper.
A Steam Punk server
A super hero themed server. Probably several to keep the Marvel vs. DC discussion from escalating.
More historical servers based on Greece, China, Japan or the Wild West.
A dark fantasy server possibly in combination with strong horror elements. Quasi Dragon Age meets World War Z. Alternatively, I could also imagine individual servers with these themes. There are enough ideas in the dark fantasy genre, and I don't think a zombie survival server is out of the question in terms of demand.
And of course there will also be several private servers, where quite a few rich, celebrities and influential people pursue their hedonistic habits, that Hedonism Bot would turn green with envy.
