Star Venture was a play-by-mail computer-moderated game set in a 125-star galaxy, in which each player has one or more starships at their disposal to use in whatever way they need.
[1] Within certain limits, players begin at their starport (called Imperia) by purchasing from a menu of available starships.
[2] In the April 1983 edition of Dragon (Issue 72), Michael Gray stated "This game is thematically quite like Star Master, though it seems to be more closely structured.
I recommend it, with a few warnings: (1) This is not a game for novices, and (2) it requires some mathematical ability and a blazing competitive will.
I also commend Schubel & Son for their lightning speed in publishing errata and in implementing player suggestions (already adding convoy and special message rules).
