VampiRing was a board game created exclusively for online play on YouPlay.it in 2004. Taken from the homepage:
Give yourself up the dark world of vampires and try an exciting adventure of monstrous metamorphosis and bloody fights! This original game, created and designed specially for our website, allows 2/4 players to lead a family of three thirsty vampires. They’ll move round among ancestral castles, obscure forests, gloomy caves, ruined towers and fearful graveyards hunting for each others. Who will be able to presage enemies’ transfigurations? Who will succeed in anticipate their moves? Who will ambush the opponent vampires to suck them the last drop of blood?
There are two versions of the game to assure different strategy levels: in the "Castle" way players can ensure their vampires into their own Homes; in the "Mansion" one vampires are safe only in the shade of the great Cross.
