OGRE / G. E. V. game Steve Jackson

OGRE / G. E. V. ..two classic games of future tank warfare, by Steve Jackson
box measures approx. 9 1/4" x 6 " x 1 1/4".... and is pretty worn. two of the small folding tabs are torn off. The game is in 'hardly played' condition and looks like new.. is complete and entirely playable.
"..Ogre is a perfect introduction to wargaming- fun and easy to learn, but still interesting every time you play. Players will find it easy to invent their own scenarios, new units and optional rules. Since the first release of the classic game in 1977, over 200,000 'Ogre/G.E.V.' games and supplements have been sold. This new* combined edition includes two-color, double sided counters, two different full-color maps, and a rulebook for both games. For 2 players (more in some scenarios), age 12 and up. Playing time 30 minutes to 2 hours."
