Diablo 3

A mysterious star has fallen on Tristram, and the undead are rising again from the cathedral seemingly cleared long ago.
Return to the grim world of Sanctuary for the third time, and take part in the eternal war between the heavens and the demon lords as one of the mighty champions capable of taking on the vicious hordes  on their own.  Hack, slash, and cast deadly spells in dark dungeons, gather powerful loot, discover synergies, and hunt uniques.
Diablo III is excellent and expansive follow-up to the classic series.
