If you like Space Games, you can't go wrong with this set! PLEASE NOTE: I am packing the Federation Space game inside the Throne world box to get all three into a smaller box.

FIRST (pics 1 through 5)

From Boardgamegeek.com:

"Federation Space" is a strategic-level Science-Fiction board-wargame set in the Star Trek universe from the original TV series. Players control an entire fleet of starships for one of eight different races of the Star Fleet universe in an attempt to destroy the fleets of their opponents. In addition to a general melee or "free for all", 26 different scenarios are provided that cover everything from a Klingon rebellion to the death of the Federation.

Tactical combat can be resolved using the simple system included or the more detailed Star Fleet Battles rules, if desired. This gives players the ability quickly resolve those conflicts that are unimportant or heavily weighted towards one side, and use the detailed Star Fleet Battles rules for engagements that are pivotal or very closely matched.

This copy is mostly punched. There are two maps for some reason. One has a small tear but the other is just fine. Everything is in good shape, though the box shows some scuffing. Up to eight players, Two hour playing time. About 10 pages of rules plus 28 scenarios to play. Made by Task Force Games, 1981. Nine pages of rules, followed by the scenarios.

From the box:

"Throneworld is a game of glactic conquest for 2-6 players, ages 12 to adult. Each player directs the expansion of one of six different alien races, starting from a single homeworld located on the outer fringe of the galaxy."

This is a strategy game involving not only space combat but also production and research. According to the box the play time is 3-6 hours. Rules are 12 pages. Includes errata. Hardback map. Box is a little scuffed of course but everything else is there and fine. Made by Prism Games,  1997.

THIRD (pics 13 through 15)

From the rules:

"In basic terms, Imperium is a scient-fiction simulation game, presenting a future history situation involving starships, industry, troops an defenses in  a campaign for supremacy among the stars."

This is the only one of the three that I've played. I really enjoyed it, playing it a number of times. Unfortunately the original box is missing and the original rules are in pretty bad shape, though they are included. I've photocopied them and put them in a folder. Though a little worn, everything is there and in fine shape. 12 pages of rules.
