[1] Space Infantry was designed by Daniel Douglas Hutto and Roger Allen Esnard, and published by D&R Game Design in 1982 as a 68-page book.
I wonder how much better Space Infantry would have been had it had an outside and objective editor: then it might have been usable.
As it is, I imagine that Space Infantry could be made into a workable roleplaying system where the gamemaster willing to use it as a base and do most of the design work himself.
But the question is, why bother when one can start from scratch or pick up one of the infinitely superior systems already available?
There's no question about one thing: Space Infantry is certainly one to pass up.
