Recently, in addition to playing the Vampires game, I have also been playing Gothador. It is similar, in that it is a grid-based MMORPG, but it isn't simply about vampires and biting.
In the Gothador realm, you battle with a myriad of mythical creatures, ranging from bats, rats and dogs to goblins, orcs and demons. There is danger lurking around every corner, and (after you get a few levels and items) it is quite fun. Good luck, and happy hunting!
Oh, and if you get stuck, you can get info on everything in the game by checking out the Guild of Wisdom.
