Tiny Frontiers is for you when you want a sci-fi exploration game quickly up and running. 'Tiny' refers to the amount of system mastery you need; it is very much a full game providing a firm framework for players and gamemasters. The system is simple but broad. Every feature is there, just in a simple and approachable form. Handwaving and fiat are necessary, but the book is very good at presenting ideas and ways for what and how you should build over the simple base mechanics.

Overall it is very well written and laid out; beginner groups should find it very suitable for themselves. The gamemaster section is especially helpful for putting together an adventure. There is a good amount of ready material, from encounter guidelines and alien artifact tables, to sixteen whole micro-settings to get your game up fast. The settings are very diverse and at least some are sure to strike your fancy.
