Legends of Aria is a pay once MMO; based off Ultima Online.
Unique to its predecessor, the game allows players to move between realms (servers) with each server having its own unique rulesets.
Level up skills like in Skyrim; as you improve your character will be able to perform those tasks with skills such as mining having better luck of materials not being lost.
All items in this game are lootable from players and stealing is a legitimate skills, but has consequences depending on where you are.
The base default map is Celador which has 4 towns connected by wizard towers which act as gateways (or moonstones as Ultima fans will know).
Legends of Aria has a "Ultima Online 2.0" server where the community has done their best to recreate Ultima Online so players can enjoy the original game which is really showing its age now (and is tricky to setup).
