Annihilator & One World

Oneworld has a diceless combat system. Annihilator is a wargame where one player sends a small force of space soldiers into a huge, robotic planetkiller, while the other player controls the planetkiller's automated defenses.[1]

In the inaugural issue of Ares Magazine, David Ritchie gave the game package a poor score of 2 out of 9, saying, "The result is a nicely balanced game which almost succeeds in overcoming the flimsiness of its premise. The two games are playable in one-half to three-quarters of an hour.".[2]

In the May-June 1980 edition of The Space Gamer (Issue No. 28), Denis Loubet reviewed Annihilator & One World was similarly unimpressed by either game. "Oneworld seems to take itself too seriously, and I don't know whether to believe the introduction or not. The counter mix is sort of unbalanced; the fog counters are of little worth, while the blades are the main attacking force... "Annihilator is just too small a game; there's not enough there. If there were more and different counters and a more complex and varied map, it might have the popularity of Ogre, but as it stands it's too small.".[1] Loubet commented that [1]

In the August 1980 edition of Dragon (Issue 40), Glenn Williams reviewed Annihilator and found "both the rationale and the mechanics of the game were poorly developed."[3]
