You have four classes : warrior, mage, assassin and vampire (I usually play as assassin). Like in any mmorpg, you are in a world and level up by fighting monsters and doing quests. I enjoyed the quest system and fighting mode in this game more than in other games. About equipment, there are possibilities to upgrade, but very costly and stuff to upgrade is sometimes rare to find. There are also instances, places where you make a team with other players to challenge bosses in order to obtain rare items.
Well I don't really know what I could tell more, just letting you discover on your own... And for the interested ones feel free to ask or discuss^^
