Wurm Online's largest current server measures 16x16 kilometers, but the developers have their eyes on a much bigger prize. Today at 10:00 p.m. Central European Summer Time (4:00 p.m. EDT), Code Club will be testing a 64x64 kilometer non-instanced mega-server.
You can join in if you like, as the Wurm devs are looking for anyone and everyone to see how many players the server can simultaneously support. No registration is required for the test.
Lead developer Rolf Jannson says that 50,000 critters will be roaming the fantasy sandbox title's wilderness during the test, which is actually "a fairly low population in Wurm terms." Jannson also says that no other MMO has launched a modifiable map of this scale, and "running this many players in one game zone is pretty unusual in itself and will be an interesting experience."
