- Lou Zocchi's Alien Space starship warfare wargame, which my Dad bought for me on one of our many trips to the Strasenburgh Planetarium. This game had cutouts of alien ships (one per 8.5" x 11" sheet, if I recall correctly. I believe range was determined by running a string between ships. I never quite figured out how to play the game; I was pretty young.
- SPI's Starforce: Alpha Centauri, a wargame of interstellar conflict among humans and a few alien species near Earth. Space travel was based on teleportation. The band the Human League took their name from this game. SPI created a very interesting setting, technology, and races for this game. There were two follow-up wargames, Starsoldier and Outreach, but it is too bad there was never a roleplaying game. One of the distinctive features of the game was that warfare primarily involved using teleportation to move enemy ships to another system. So, actual violence wasn't necessary in space (however the Xenophobes, a race with Nova bombs, had another quite genocidal strategy. The setting was particularly influential in the space empires that my friends and I created in the years before Traveller.
- A hyperspace movement-based strategy game, whose name I have forgotten. With this game, the longer your ships stayed in hyperspace, the more of the game board was available to you when you chose to exit hyperspace. So in other words, hyperspace movement is a form of expanding potential energy until it is committed to a spacial expression upon exiting hyperspace. I don't even want to think about what happens if a ship isn't able to exit for some reason. Come to think of it, this would be excellent to implement in a FATE space opera game. If anyone knows what that game is, please feel free to drop me a line in the comments!
So what were yours?
