It's an older MMORPG style if you are into that sort. It's notoriously a grindy game taking forever to max out levels but it's a good time waster if you don't mind the graphics. There's an upgraded HD version that gives you a little better experience you can use.
There's fishing, crafting, woodcutting, you got your basic combats too, mage, range, melee. There's some unique features to the game like runecrafting. Eh all in all it's not a bad game. Probably a little something for everyone in there. Raids, quests, skills, leveling.
