God damn Sacrifice, it was an RTS-esque third-person wizard game from 2000 or so. I remember the story and voice acting being quite good, and everything in that game being extremely weird looking. You could pick your god (thunder, fire, stone, life, and death IIRC) and they all had different spells and minions. You needed souls to summon minions, and you could get more souls by battling the other wizards' minions and stealing their souls, by having some strange dudes with giant syringes take the souls and perform a ritual at one of your altars. The highest level spells were fucking awesome too, if you played as a fire wizard you could summon a giant god damn volcano on the battlefield. The goal was to sacrifice one of your minions at an enemy wizards main altar, and banish them from the realm (i.e. eliminate them from the game).
And holy fuck I've also just been informed that this game is available on Steam, brb
