 "Gex" was one of the best-selling 3DO games, but the exact sales figures remain unclear.In July 1995, roughly a month before it became a pack-in game, its sales exceeded one million units according to "GamePro" and "Electronic Gaming Monthly".Contradictory to this, an article in "Next Generation" cover-dated November 1995 says that the 3DO version had sold only 750,000 units worldwide.
