I'd like to try Ulm.
If you have any questions I'd be glad to help. I'm in the middle of hosting my first game on llamaserver and so far things have gone smoothly (well the hosting at least
).
Worthy Heroes is included with CBM 1.4. I read that there are some bugs in 1.4 but I think the fixes are coming soon. You may want to wait until then before putting the game up.
