Many people (especially here) actually prefer Titan Quest to Diablo 2. Grim Dawn is without question the main successor to Diablo 2 in every way. I know we have had some limited discussion of this game before, but with a new expansion on the horizon (Forgotten Gods), and this forum's general love of the loot-hunt, ARPG genre, it is really time to give this game it's due.
