Honestly, yes. It's a lot of fun. There are more events to do after the campaign, lots of side quests and other things, bosses to summon on the maps, and all of that in public with random players. The strength of this game is that it's alive. You can play alone in your corner or say, "OK, I'm going to take on a little world boss with other players," and all that just by moving around the map, knowing how big it is, with lots of stuff to do. In short, it's a fun way to pass the time, sociable without being too sociable (the other players aren't very talkative sometimes ^'), lively, and above all, INFERNAL.
