As in other MMOs, you can play solitary adventurer (PVE = versus-Environment) or by forging friendly or combative relationships with other players (PVP = Character versus Character). Playing alone can be boring, while group play may result in a network of binding obligations. We progress by killing "monsters" (the characters and animals run by the computer) or other players, or doing quests (missions) alone or in groups, but you can also collect various ingredients to make the crafts and especially trading in a network of selling hotels. You can create multiple characters by combining races and professions, and explore a vast and varied world. The graphics are beautiful, with a very distant realistic style like "cartoon" competitor game "World of Warcraft".
The problem is that you often play in progress, and it quickly becomes addictive.
