#RPGaDAY2015 Day 18: Favorite Sci-fi RPG

Mongoose Traveller is my favorite sci-fi rpg.  I feel that the rules do a good job of evoking the feel of Classic Traveller while bringing in some modern game design.  I like that the core rule book covers everything you need, and I like the fact that they give you three different types of interstellar travel so that you can customize space travel to your universe.  I ran a play-by-forum game of Mongoose Traveller and I loved how the rules would fall into the background.  There is a free quickstart if you have never looked at the game.  Mongoose Traveller , my choice for RPGaDAY 2015 day 18.
