I see "some" similarities with the World of Warcraft which isn't a problem at all. There are better and worse things in this game. Overall it's a pretty good game with a few annoying stuff, like the maximum altitude or annoying solo boss fights.
Unfortunately the game is not running properly on xbox. A journey to Velika means (100%, no exception) an automatic drop out. The game also stops in random situations, you're just never safe.
Most annoying thing in the game when you have those boxes from the events with some seriously good stuff, there's no preview whatsoever to chose the one you really like. You just pick one by its name, blindly and hope that they look OK. Also, you can't keep them forever, they last only for a few weeks.
Database is nowhere near as good as the one for Wow.
Quests sometimes are annoying but in overall enjoyable, dungeons, solo and multi player ones too are OK. Players are pretty helping, that's what you can't really say about Wow.
Takes some time to understand how the game works and quite time consuming but I think it is a really good game.
