There was also Driller in 1987 which had full 3D representations though you could rarely take advantage of it. It was based on the Freescape technology which I played with in 3D Construction Kit in 1991 and that was definitely full 3D in terms of movement (though not a game in itself).

Was this similar to Oblivion? Where you had to plant some gas valves to relieve the pressure on the planet? Awesome, frustrating little game :)
