I any event, you can play the game as is or make custom modules and even create replicas of your old Ultima games. I am in the process of creating some interesting levels. Keep an eye open for updates. Next version should teleports based on moon phase.
Current version has updated shopkeepers.
This version sports the ability to find weapons, helms, shields, and armour under any tile. Buckaneers Den town is completed. Britain is next. Look for this in the next several versions. I am considering releasing the completed town on Buckaneers Den and other maps so you can try them out.
