I didn't know Blizzard was affiliated with Diablo but now I come to think of it of course it was. Half life was the best selling game for three years until Rome Total War took it off the top spot. Personally I've played Medievil Total War 2 which is released on the 10th of November and it is fucking incredible if you like planning strategic murder and fiendish battle plans. Mmorpgs just arn't what they were with people cheating.
