My personal favorite RPG system. The revised version very much improves on the what was alreay great in the first and removes some of the obtuse systems (Like combat both in space and land).
Well written and simple game. I have used it to lure many players into playing RPG's do to the flexibility of the format. The conversion guide helps to transition to the more complete (IMO) core version.
Excellent system and well layed out rules for both the players and the GM. Overall great game. I still struggle with understanding crafting but I am not sure if that is my lack of understanding or if the instructons are not obvious .
