Sacred is from Ascaron, German publisher AFAIK.

Is compared to Diablo, controls are like diablo 2, six heroes: Galdiator, Wood-Elf (ranger), Mage, Seraphim (fight and magic), Darkelf (survivor and magic), female vampire (fighter at day, bat at night).
A super-demon was summoned by a mage who lost control over him - you have to "escort" him back whence he came from. This is the main quest and about 200 sub-quests.
