("Ground Effect Vehicle") is a science fiction board wargame that simulates combat in the near future between armored hovercraft, supertanks and other futuristic weaponry.

The new game expanded the GEV gameplay and gave scenarios fitted to a high-speed vehicle.

[1] This could be used for either hit-and-run attacks with a retreat phase out of range, or a charge emphasizing a high-speed advance, even without time to adequately defend.

In 1977, Metagaming Concepts published Ogre and pioneered the microgame, a small, cheap and simple solitaire or two-player game, often with a science fiction or fantasy theme.

Ogre was created by Steve Jackson, who then designed a sequel, G.E.V., which was published by Metagaming as their 6th MicroGame in 1977.

In the inaugural issue of Ares (March 1980), David Ritchie commented that "GEV is not as clean as Ogre, but probably has more replay value.

"[5] In Issue 30 of Phoenix, (March–April 1981), Michael Stoner thought it was a very quick-moving game, noting that in most scenarios, one player gains the upper hand within ten minutes of play.

Only when Ogres are added and the situation is reduced to the uncomplicated objectives of the earlier game does it come to life."
