Science fiction wargames
I am not generally a missive fan of science
fiction wargames, normally happier dabbling in
historical games, but a few SF games do stand out
as worthy of repeat play.
Triplanetary by GDW
Probably the best board game ever made. The rules are so simple, but it proves a challenging game to master. Any game that can keep you amused for hours, despite only having one counter for each player, deserves praise.

Traveller by GDW
Like Dungeons and Dragons...but with more thinking.
For further details see wikipedia
Full Thrust
A fun miniatures game. Anything with vector movement is worth playing (see Triplanetary above!).

For an example of a game see the Full Thrust page.
