A server with old time guns that take a few seconds to reload per shot and swords that can be used to repel the bullets. This way you have a nice way to defend against bullets, and also don't have bullets spraying everywhere. The time period would be based around the early 1800's. There would be jobs as a blacksmith forging weapons, a bartender serving drinks, bounty hunter catching wanted NPC baddies, and more. There would be carriage riders that allow you to travel from one city to another at a faster rate for a small fee. I'm tempting myself.
