The game employs a voxel-based graphics engine. Porter told Ion Storm the game would take 6 weeks to finish but hired an expensive full-time team out of ex-7th Level people. It was renamed Dominion Storm and later Dominion: Storm Over Gift 3.
Ion Storm unanimously voted in August 1997 to buy Dominion for $1.8m dollars from 7th Level, to 'burn' one of the 6 game 'options' that Ion Storm had contracted with Eidos, as part of a royalty deal, but Porter thought the game was 'a top-10 product' that could sell 500,000 copies. Porter wanted to make the game Doppelganger at Ion Storm but heard that 7th Level had Dominion up for sale in 1997 because it was leaving the industry. Porter and O'Flaherty started Dominion, based on G-Nome at 7th level before leaving, and John Romero hired them to start Ion Storm. Distant Thunder made G-Nome which 7th Level published in 1996, which sold badly and flopped in reviews. Dominion was first made by Todd Porter and Jerry O'Flaherty's company Distant Thunder, that was sold to 7th Level in February 1995.
